Hydropower can be a source of sustainable energy, provided environmental considerations are taken into account and economic aspects of hydropower design are appropriately addressed. Using concrete-lined pressure tunnels instead of steel pipes may be economically attractive but may also have limitations due to the low tensile strength of concrete. Cracking in concrete tunnel linings can lead to loss of energy production, extensive repairs, and even accidents. One of the techniques available to improve the bearing capacity of pressure tunnels is through prestressing the concrete lining by grouting the circumferential gap between the concrete lining and the rock mass at high pressure. A classical approach to determine the bearing capacity of such tunnels is based on the theory of elasticity, assuming impervious concrete. In this research, a new concept is introduced to assess the effect of seepage on the bearing capacity of pressure tunnels. Also, an innovative approach is proposed to explore the effects of the in-situ stress ratio on the lining performance. Distinction is made based on whether the rock mass behaves as an elasto-plastic isotropic, or elastic anisotropic material. Furthermore, a simplified method is introduced to quantify seepage associated with cracks around the tunnel, which is useful for assessing tunnel stability.

Effectively Calculate the Pressures of Soil

When it comes to designing and constructing retaining structures that are safe and durable, understanding the interaction between soil and structure is at the foundation of it all. Laying down the groundwork for the non-specialists looking to gain an understanding of the background and issues surrounding geotechnical engineering, Earth Pressure and Earth-Retaining Structures, Third Edition introduces the mechanisms of earth pressure, and explains the design requirements for retaining structures. This text makes clear the uncertainty of parameter and partial factor issues that underpin recent codes. It then goes on to explain the principles of the geotechnical design of gravity walls, embedded walls, and composite structures.

What s New in the Third Edition:

The first half of the book brings together and describes possible interactions between the ground and a retaining wall. It also includes materials that factor in available software packages dealing with seepage and slope instability, therefore providing a greater understanding of design issues and allowing readers to readily check computer output. The second part of the book begins by describing the background of Eurocode 7, and ends with detailed information about gravity walls, embedded walls, and composite walls. It also includes recent material on propped and braced excavations as well as work on soil nailing, anchored walls, and cofferdams. Previous chapters on the development of earth pressure theory and on graphical techniques have been moved to an appendix.

Earth Pressure and Earth-Retaining Structures, Third Edition is written for practicing geotechnical, civil, and structural engineers and forms a reference for engineering geologists, geotechnical researchers, and undergraduate civil engineering students."

Reinforced concrete is the most widely used construction material in the world, and extended performance is rightly expected. Many structures are in aggressive environments, of critical importance and may be irreplaceable, so repair and protection are vital. This book surveys deterioration of concrete, particularly corrosion of the steel reinforcement, and the various chemical, biological, physical and mechanical causes of deterioration. It outlines condition survey and diagnosis techniques by on-site and laboratory measurements. It sets out mechanical methods of protection and repair, such as patching, inhibitors, coatings, penetrants and structural strengthening as well as cathodic protection and other electrochemical methods. This book also gives guidance on preventative measures including concrete technology and construction considerations, coatings and penetrants, alternate reinforcement, permanent corrosion monitoring and durability planning aspects. Asset managers, port engineers, bridge maintenance managers, building managers, heritage structure engineers, plant engineers, consulting engineers, architects, specialist contractors and construction material suppliers who have the task of resolving problems of corrosion of steel reinforced concrete elements will find this book an extremely useful resource. It will also be a valuable reference for students at postgraduate level. Authors The late Professor Brian Cherry of Monash University, Melbourne, Australia was one of the world's leading corrosion science and engineering educators and researchers. Warren Green of Vinsi Partners, Sydney, Australia is a corrosion engineer and materials scientist. He is also an Adjunct Associate Professor.

Rock falls can be a public safety issue. This book provides comprehensive information on identification of these hazards, and design and construction of protection methods. Rock Fall Engineering describes first, the theoretical background to rock fall behavior in terms of the impact and trajectory phases of rock falls, and second, how this information is applied to modeling of rock falls and the design of ditches, fences and sheds. The theory of rock fall behavior is verified by comparing the calculations with five carefully documented case studies.The book covers four main topics as follows: Describes causes of rock falls, including geology, climate and topography, and provides detailed documentation on rock fall impacts and trajectories at five sites with a wide variety of topographic and geologic features Discusses theory of impact mechanics, and its application to velocity and energy changes during impacts and trajectories Reviews methods of modeling rock fall events, and presents analyses for the five case studies Examines rock fall protection in terms of selecting appropriate method(s) for site conditions, and design principles in which the objective is to absorb impact energy in an efficient manner This book, which contains many worked examples, is of interest to practitioners and researchers working in the fields of geological engineering and natural hazards. Duncan C. Wyllie is a principal with Wyllie & Norrish Rock Engineers in Vancouver, Canada, and a registered professional engineer in British Columbia. He has worked on rock fall hazard projects involving the design and construction protection measures since the 1970s. He is the author of Foundations on Rock, Second Edition, and Rock Slope Engineering, Fourth Edition, both published by CRC Press.

This book contains detailed coverage of the basic theory of reinforced and prestressed concrete, and demonstrates a wide range of practical applications of reinforced and prestressed concrete, with numerous examples, design-curves, and diagrams.

The structural challenges of building 800 metres into the sky are substantial, and include several factors which do not affect low-rise construction. This book focusses on these areas specifically to provide the architectural and structural knowledge which must be taken into account in order to design tall buildings successfully. In presenting examples of steel, reinforced concrete, and composite structural systems for such buildings, it is shown that wind load has a very important effect on the architectural and structural design. The aerodynamic approach to tall buildings is considered in this context, as is earthquake induced lateral loading. Case studies of some of the world's most iconic buildings, illustrated with full colour photographs, structural plans and axonometrics, will bring to life the design challenges which they presented to architects and structural engineers. The Empire State Building, the Burj Khalifa, Taipei 101 and the HSB Turning Torso are just a few examples of the buildings whose real-life specifications are used to explain and illustrate core design principles, and their subsequent effect on the finished structure.

This book treats the subject of local scour around different kinds of marine structures, exposed to waves and/or currents. The first, major part of the book is devoted to marine pipelines, describing in detail all kinds of scour scenarios, and also making recommendations for scour protection. Other kinds of structures considered are single piles (slender or large), groups of piles, complex subsea structures, breakwaters, and seawalls. The scour due to ship propellers is also described. The book deals mainly with the scour in noncohesive sediment but, whenever possible, available literature on the scour in finer sediment has been incorporated. In addition, a chapter on the impact of wave-induced liquefaction is included.The authors' aim is to describe in detail the hydrodynamic processes causing the erosion. With a hydrodynamic understanding, it is easier for the consulting engineer to predict scour in those many cases where physical model tests are not available.

Numerical Methods in Geotechnical Engineering contains the proceedings of the 8th European Conference on Numerical Methods in Geotechnical Engineering (NUMGE 2014, Delft, The Netherlands, 18-20 June 2014).

Virtual worlds are places where humans interact, and as such they can be environments for research and learning. However, they are complex and mutable in ways that more controlled and traditional environments are not. Although computer-mediated, virtual worlds are multifaceted social systems like the offline world, and choosing to study virtual world phenomena demands as much consideration for the participants, the environment and the researcher as offline.

By exploring virtual worlds as places of research and learning, the international practitioners in this book demonstrate the power of these worlds to replicate and extend our arenas of research and learning. They focus on process and outcomes and consider questions that arise from engaging in teaching and research in these spaces, including new approaches to research ethics, internationalization, localization, and collaboration in virtual worlds.

This book was originally published as a special issue of Learning, Media & Technology.

The 8th International Conference on Physical Modelling in Geotechnics (ICPMG2014) was organised by the Centre for Offshore Foundation Systems at the University of Western Australia under the auspices of the Technical Committee 104 for Physical Modelling in Geotechnics of the International Society of Soil Mechanics and Geotechnical Engineering. This quadrennial conference is the traditional focal point for the physical modelling community of academics, scientists and engineers to present and exchange the latest developments on a wide range of physical modelling aspects associated with geotechnical engineering.

Fundamental aspects of earthquake engineering, geohazards, ground reinforcements and improvements, and soil properties and behaviour are also covered, demonstrating the increasing complexity of modelling arising from state-of-the-art technological developments and increased understanding of similitude principles. A special theme on education presents the latest developments in the use of physical modelling techniques for instructing undergraduate and postgraduate students in geotechnical engineering.

We all depend on infrastructure for civilised living with the scale and sophistication of what we build ever increasing. Manifestly we all have a vested interest in construction being safe, and yet failures occur. Not infrequently these failures are catastrophic and accompanied by huge cost and occasional loss of life. Avoiding such tragedies is every engineer's desire but how to do it is not straightforward. Nor is it straightforward to respond the question of: is this project safe? Nonetheless, progress can be made by laying down guidelines of what makes structures safe and by studying the pattern of past failures as a basis for predicting what might go wrong. This assists by drawing on the author's considerable career experiences of observation, study and practice. The opening chapter describes the general challenges of making structures safe taking account of uncertainty and the consequence of failure, and it also describes the evolution of safety thinking which nowadays includes issues of worker safety and health. Subsequent chapters discuss what is meant by both failure and safety and describe various safety attributes that ought to be targeted. Even over the last 50 years, structural methodologies for analysis and design have evolved to reflect the way we collectively think is the best to assure safe structures. Many of the notions used are rather abstract and so can best be appreciated by learning from what has gone wrong in the past. Unfortunately there is no shortage of precedents. Hence all subsequent chapters covering human error, material failures, construction failures and fire follow a general pattern of describing the problem, accompanied by examples illustrating how failures have arisen in practice. It will be apparent that common themes recur. Engineered structures protect societies, so some of the biggest challenges we face are of designing against the possibility of man-made or environmental catastrophe. Most readers will be familiar with the occurrence of natural events such as storm, flood and earthquake and so two chapters are devoted to man-made and natural hazards. Occupational health and safety, plus designers' legal obligations to assure these, are described in another chapter. The final chapter concerns Avoiding Failure and deals with concepts such as hazards and risk and the procedures that can be followed to minimise the probability of serious failure occurring.

Fiber-reinforced polymer (FRP) composites have become an integral part of the construction industry because of their versatility, enhanced durability and resistance to fatigue and corrosion, high strength-to-weight ratio, accelerated construction, and lower maintenance and life-cycle costs. Advanced FRP composite materials are also emerging for a wide range of civil infrastructure applications. These include everything from bridge decks, bridge strengthening and repairs, and seismic retrofit to marine waterfront structures and sustainable, energy-efficient housing. The International Handbook of FRP Composites in Civil Engineering brings together a wealth of information on advances in materials, techniques, practices, nondestructive testing, and structural health monitoring of FRP composites, specifically for civil infrastructure.

With a focus on professional applications, the handbook supplies design guidelines and standards of practice from around the world. It also includes helpful design formulas, tables, and charts to provide immediate answers to common questions. Organized into seven parts, the handbook covers:

• FRP fundamentals, including history, codes and standards, manufacturing, materials, mechanics, and life-cycle costs
• Bridge deck applications and the critical topic of connection design for FRP structural members
• External reinforcement for rehabilitation, including the strengthening of reinforced concrete, masonry, wood, and metallic structures
• FRP composites for the reinforcement of concrete structures, including material characteristics, design procedures, and quality assurance quality control (QA/QC) issues
• Hybrid FRP composite systems, with an emphasis on design, construction, QA/QC, and repair
• Quality control, quality assurance, and evaluation using nondestructive testing, and in-service monitoring using structural health monitoring of FRP composites, including smart composites that can actively sense and respond to the environment and internal states
• FRP-related books, journals, conference proceedings, organizations, and research sources

Comprehensive yet concise, this is an invaluable reference for practicing engineers and construction professionals, as well as researchers and students. It offers ready-to-use information on how FRP composites can be more effectively utilized in new construction, repair and reconstruction, and architectural engineering."

All the traces of historic heritage are a fundamental part of our environment and reward us in the form of cultural enrichment, with the ability to have a positive effect both on our lifestyle and economy. Therefore, the preservation of ancient monuments, historic towns and sites has increasingly drawn the attention of public opinion, governmental agencies as well as consultants and contractors. This interest must be however carefully controlled and directed, since the conservation of monuments and historic sites is one of the most challenging problems of our age. Careless attempts at preservation can be detrimental not only to their iconic value (formal integrity), but even to their structural characteristics and the materials they are built with (material integrity). Geotechnical Engineering for the Preservation of Monuments and Historic Sites collects one opening address, four special lectures and 82 contributions from all over the world, giving a unique sample of the geotechnical problems to be tackled, the solutions currently being proposed, and the strategies being carried out to preserve the overall integrity of monuments and historic sites. It is clearly apparent that differences exist around the world not only in terms of the characteristics of the monuments or sites to be preserved, but also in the approaches adopted to achieve this aim. Hence, no unique solution is available to the geotechnical engineer dealing with the delicate structures and sites that represent our cultural heritage, and knowledge of previous experiences may be a unique guide in any technical decision-making process.

A detailed view on the effects of seismic activity on tank structures As the use of aboveground and underground storage tanks (ASTs and USTs) continues to grow--with approximately 545 thousand in the US alone--the greatest threat to from AST and USTs is the contamination of groundwater, a vital source of drinking water throughout the world and one that close to half of Americans rely upon. These tanks suffer a great deal of strain during an earthquake, as a complicated pattern of stress affects them such that poorly designed tanks have leaked, buckled, or even collapsed during seismic events. Furthermore in oil and gas industrial plants, the risk of damage is even more critical due to the effect of explosion, collapse, and air or soil contamination by chemical fluid spillages. Seismic Design and Analysis of Tanks provides the first in-depth discussion of the principles and applications of shell structure design and earthquake engineering analyses focused on tank structures, and how these methodologies can help prevent the destruction of AST and USTs during earthquakes. Providing a thorough examination into the design, analysis, and performance of steel, reinforced concrete, and precast tanks, this book takes a look at tanks that are aboveground, underground, or elevated, anchored and unanchored, rigid or flexible, and evaluates the efficacy of each method during times of turbulence--and it does so without getting bogged down with impenetrable math and theory. Seismic Design and Analysis of Tanks readers will also find: Global approach for the best analytical and practical solutions available in each region: Discussion of the latest US codes and standards from the American Society of Civil Engineers (ACSE 7), American Concrete Institute (ACI 350,3, 371.R), American Water Works Association (AWWA D100, D110, D115), and the American Petroleum Institute (API 650) An overview of European codes and standards including Eurocode 8-4 and CEN-EN 14015 Hundreds of step-by-step equations accompanied by illustrations Photographs that feature real-world damage to tanks caused by seismic events Perfect for practicing structural engineers, geotechnical engineers, civil engineers, and engineers of all kinds who are responsible for the design, analysis, and performance of tanks and foundations--as well as students studying engineering--Seismic Design and Analysis of Tanks is a landmark text, the first work of its kind to deal with seismic engineering performance of storage tanks.

: Conservation of monuments and historic sites is one of the most challenging problems facing modern civilization. It involves various cultural, humanistic, social, technical, economical and administrative factors, intertwining in inextricable patterns. The complexity of the topic is such that guidelines or recommendations for intervention techniques and design approaches are difficult to set. The Technical Committee on the Preservation of Monuments and Historic Sites (named TC19) was established by the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) in 1981, is supported by the Italian Geotechnical Society (AGI), and renamed TC301 in 2010. Geotechnics and Heritage, collects relevant case histories on the role of geotechnical engineering in the preservation of monuments and historic sites, and is an addition to the Proceedings of the two International Symposia organized by the Committee in Napoli in 1994 and 2013. The contributions in the book proof the significant role geotechnical engineering plays in conservation of historic building and monuments.
