This publication will introduce you to methods, materials and equipment for stabilization of subgrade soils. The depth of stabilization generally must be sufficient to absorb most of the foundation pressure bulb. The relative benefits of vibrocompaction, vibrodisplacement compaction, and precompression are discussed. Soft, cohesive soils treated in place are generally suitable only for low-intensity loadings. Soil stabilization of wet, soft soils may be accomplished by addition of lime; grout to control water flow into excavations to reduce lateral support requirements or to reduce liquefaction or settlement caused by adjacent pile driving; seepage control by electroosmosis; and temporary stabilization by freezing.

A comprehensive book focusing on the Force Analogy Method, a novel method for nonlinear dynamic analysis and simulation This book focusses on the Force Analogy Method, a novel method for nonlinear dynamic analysis and simulation. A review of the current nonlinear analysis method for earthquake engineering will be summarized and explained. Additionally, how the force analogy method can be used in nonlinear static analysis will be discussed through several nonlinear static examples. The emphasis of this book is to extend and develop the force analogy method to performing dynamic analysis on structures under earthquake excitations, where the force analogy method is incorporated in the flexural element, axial element, shearing element and so on will be exhibited. Moreover, the geometric nonlinearity into nonlinear dynamic analysis algorithm based on the force analogy method is included. The application of the force analogy method in seismic design for buildings and structural control area is discussed and combined with practical engineering.

This publication concerns (a) immediate settlements, (b) long-term settlements, (c) rate of settlement, (d) criteria for tolerable settlement, (e) methods of reducing or accelerating settlements for saturated fine-grained soils and (f) methods for controlling and/or estimating heave in swelling soils. Procedures given are for fine-grained compressible soils as well as for coarse-grained soils. The settlement of saturated cohesive soil consists of the sum of three components; (1) immediate settlement occurring as the load is applied, (2) consolidation settlement occurring gradually as excess pore pressures generated by loads are dissipated, and (3) secondary compression essentially controlled by the composition and structure of the soil skeleton. The settlement of coarse-grained granular soils subjected to foundation loads occurs primarily from the compression of the soil skeleton due to rearrangement of particles. The permeability of coarse-grained soil is large enough to justify the assumption of immediate excess pore pressure dissipation upon application of load. Settlement of coarse-grained soil can also be induced by vibratory ground motion due to earthquakes, blasting or machinery, or by soaking and submergence.

Dieses Buch beschreibt eingangs den Lebensraum des Sediments fur die Biozoenose sowie die biologischen und chemisch-physikalischen Aspekte, welche die Bioverfugbarkeit von Schadstoffen steuern. Aus Flussen, AEstuaren und Hafen mussen Sedimente beseitigt werden, weil sie die Schifffahrt und den Hochwasserabfluss beeintrachtigen. Ein zweiter Schwerpunkt des Buches behandelt daher die Rolle des Sediments als Baggergut und die sich daraus ergebenden Probleme der Grenzwertfindung, die Entwicklung von Handlungskriterien, Zielvorgaben und Klassifizierungen fur eine Umlagerung. An zahlreichen Fallbeispielen werden Loesungs- und Bewertungsansatze aufgezeigt. Im dritten Teil des Buches werden vom Fachausschuss Gewassersedimente in der Wasserchemischen Gesellschaft der GDCh Handlungsempfehlungen abgeleitet und eine integrierte Bewertungsstrategie fur Sedimente vorgeschlagen, die biologische und oekologische Merkmale mit chemischen Bewertungskriterien verknupft.

On March 11, 2011, a magnitude 9.0 earthquake rumbled off the east coast of Japan, followed by a tsunami that generated waves more than 18 meters high. The earthquake and tsunami caused devastation throughout the Tohoku and Sendai regions of Japan, killing nearly 16,000 people and causing damage estimated at more than US$126 billion. For seven days in May 2011, an ASCE/COPRI Coastal Structures Team investigated the earthquake and tsunami effects specific to engineered coastal structures, coastal landforms, and coastal processes in northeast Japan. Joined by colleagues from Japan's Port and Airport Research Institute, the survey team observed five categories of coastal protection structures: coastal dikes, tsunami seawalls, floodwater gates, breakwaters, and vegetated greenbelts. This report provides background to the field investigation, including an event summary, the tectonic and geologic setting, and the generation, propagation, and runup of the tsunami. It then describes 11 mechanisms causing damage or failure and includes photographs illustrating the effects each mechanism. Finally, the report presents lessons learned regarding what worked and what didn't and how this knowledge can be used to engineer against future natural disasters. For coastal engineers, structural engineers, geotechnical engineers, and disaster risk managers, the observations and analysis in this report provide critical information for engineering infrastructure that withstands major earthquake and tsunami events.

Supersedes FM 5-410, 23 December 1992.Construction in the theater of operations is normally limited to roads, airfields, and structures necessary for military operations. This manual emphasizes the soils engineering aspects of road and airfield construction. The references give detailed information on other soils engineering topics that are discussed in general terms. This manual provides a discussion of the formation and characteristics of soil and the system used by the United States (US) Army to classify soils. It also gives an overview of classification systems used by other agencies. It describes the compaction of soils and quality control, settlement and shearing resistance of soils, the movement of water through soils, frost action, and the bearing capacity of soils that serve as foundations, slopes, embankments, dikes, dams, and earth-retaining structures. This manual also describes the geologic factors that affect the properties and occurrences of natural mineral/soil construction materials used to build dams, tunnels, roads, airfields, and bridges. Theater-of-operations construction methods are emphasized throughout the manual. Profusely illustrated throughout.

Herbert Hoover was a Mining Engineer and author before becoming President of the United States of America during the great depression of the 1930s. This book is fully illustrated and comes with an index. In the Preface, Hoover describes the book in this way: "This volume is a condensation of a series of lectures delivered in part at Stanford and in part at Columbia Universities. It is intended neither for those wholly ignorant of mining, nor for those long experienced in the profession."

The text is organized in two parts - Part I (Soil mechanics) and Part II (Foundation engineering): Part I includes the basic properties and strength of soil, vertical and lateral pressures, discussion on earthen dam, sheet piles, and stability analysis for hill slope in connection with hill road construction. Part II discusses shallow and deep foundations, approaches of analysis of machine foundation, and various methods of determining the bearing capacity of soil. A separate chapter is devoted to on-site investigation. Besides the undergraduate students, this compendium will also be useful for students appearing for various competitive examinations such as GATE, IES and IAS. Consulting engineers in geotechnical engineering may also use this book as a reference.

The goal of the Compaction Grouting Consensus Guide is to promote good practice in compaction grouting. Compaction grouting is a ground improvement technique that increases the density, strength and stiffness of the ground through slow, controlled injections of low-mobility grout that compacts the soil as the grout mass expands. Compaction grouting can be applied equally well above or below the water table. The technology can be applied to a wide range of soils, in most cases being used to improve the engineering properties of poorly compacted fills and loose native soils. This guide covers both the practical and engineering aspects of compaction grouting and is essential reading for anyone interested in specifying, designing, and/or undertaking compaction grouting.|The goal of the Compaction Grouting Consensus Guide is to promote good practice in compaction grouting.
