Nowadays, demands on modern civil engineering structures require not only safe technical solutions, but also additional approaches, involving ecological, sociological and economical aspects. This book reacts on these new requirements with a focus on earth structures for transport engineering, mainly for motorways and railways. Technical demands have to be adequately related to the risk with which the design and execution are connected. Soil used for the construction, together with subsoil, are natural materials with a high degree of inhomogeneity. Therefore, the risk when constructing with such materials is much higher than for structures utilizing man-made materials. The engineering approach is firstly focused on the geotechnical risk identification and subsequently on the reduction of this risk. Geotechnical risk is linked to the uncertainties for individual phases of the design and construction processes. Ground model, geotechnical design model, calculation model and structure execution are the main phases of the above-mentioned processes. Risk reduction involves the lowering of the range of uncertainties for individual phases, guaranteeing safe and optimal technical solutions. Eurocode 7 "Geotechnical design" creates a general frame of this risk identification and reduction approach. Earth structures are offering great opportunities for sustainability approach. Therefore, the possibilities how to decrease consumption of land (greenfields), energy and natural aggregates are at the centre of interest. In parallel to sustainability, the principles of availability and affordability for transport infrastructures are discussed. The main aim there is to eliminate the impact of interaction of the transport infrastructure with natural and man-made hazards, thus guaranteeing long-term functionality. This book will be of interest to specialists responsible for transport infrastructure planning, investors (project owners) of motorways and railways and environmental engineers. The main focus is on those responsible for geotechnical investigations, earth structures design and on contractors of such structures.

Soil represents the oldest and most-used building material, yet up to now the subject of earthen structures has not been fully addressed. This book describes the principles of soil as construction material including its treatment using geosynthetics and stabilization. The book focuses on the principles, logic of processes, understanding of the most important problems, so that all participants in the construction project can build earth structures more safely and economically.

Soil represents the oldest and most used building material. Current paradox is that up to now this subject of Earth structures was not fully covered. This book describes the principles of soil workability as construction material including two basic forms of its treatment using geosynthetics and stabilization. It describes logics of design and control of Earth structures that significantly differ from other building materials, which brings more uncertainty and risk. Therefore Earth structures are still offering wider space for detailing the design and improvement of financial calculations quality.

Following the general part, where the principles of limit states according to Eurocode 7 - Geotechnical design are also described in more detail, the book concentrates on earth structures of transport, water and environmental projects. The parts devoted to transport projects covers in more details limit states of stability and deformation. The part devoted to water engineering prioritizes the limit state of internal erosion. The part regarding earth structures of environmental structures describes new phenomenon where part of the structure is created from non standard materials, usually susceptible to internal collapse, double porosity, unsaturation, etc. It also concentrates on protection of the surrounding from contamination.

The book focuses on the principles, logic of processes, understanding of the most important problems, so that all participants of the construction (client, designer, contractor and supervisor) are able to build these earth structures more safely and economically.
