The solution of stress analysis problems through numerical, computer oriented techniques is becoming more and more popular in soil and rock engineering. This is due to the ability of these methods to handle geometrically complex problems even in the presence of highly nonlinear material behaviour, characterizing the majority of soils and rocks, and of media consisting of two or more phases, like saturated and partially saturated soils. Aim of this book is to present to researchers and engineers working in the various branches of geomechanics an updated state of the research on the development and application of numerical methods in geotechnical and foundation engineering. Particular attention is devoted to the formulation of nonlinear material models and to their use for the analysis of complex engineering problems. In addition to the constitutive modelling, other topics discussed concern the use of the finite element and boundary element methods in geomechanics; the dynamic analysis of inelastic and saturated soils; the solution of seepage, consolidation and coupled problems; the analysis of soil-structure interaction problems; the numerical procedures for the interpretation of field measurements; the analysis of tunnels and underground openings.

NUMOG X reflects the current research and advances made in the application of numerical methods in geotechnical engineering. The papers are organised in the following four sections: 1. Constitutive relations for geomaterials 2. Numerical algorithms: formulation and performance 3. Modelling of transient / coupled problems 4. Application of numerical techniques to practical problems Many new developments on a wide variety of topics have been reported at this Symposium. These include: description of mechanical properties of soil, instabilities in soil behaviour; laboratory testing and identification of material parameters, hydro-mechanical coupling in relation to problems of nuclear waste disposal and applications of numerical methods to the analysis of tunnels, embankments, slopes and foundations. A special section is devoted to applications incorporating the tools of computational intelligence. A number of papers describe case histories of practical applications. These proceedings of the Tenth International Symposium on 'Numerical Models in Geomechanics', NUMOG X, held in Rhodes, Greece, 25-27 April 2007, contain 104 papers which were selected for presentation. The wealth of information in these proceedings should be of interest to students, researchers as well as practising engineers.

Linear mathematical assumptions for procedures in other branches of engineering have little relevance for geoengineering, which must accommodate non-linear behaviors. Contributors to eight papers apply the breakthrough numerical modeling Distinct Element Method (Cundall, late 1960s). The design philosophy for structures or excavations in geotechnical engineering is different from that followed for fabricated materials like steel and concrete. The designer has little data both with regard to geological weaknesses and strength and deformation characteristics of materials before finalizing the designs. Also these characteristics vary from place to place. In-situ stresses due to gravity and tectonics and transient forces imposed due to rainfall and earthquakes make the matter more complicated. The pore waters carry the load initially before passing it on to the solids. For the analytical procedure, to be realistic, it should account for large displacements and non-linear behaviour including strain-softening. Because of these considerations, the designers have followed procedures based on simplifying assumptions such as linear, small strain, elastoplastic behaviour. Numerical procedures based on such assumptions, though very popular in other branches of engineering, have made little impact in geo-engineering. An attempt has been made in this book to compile the recent use of distinct element codes for solutions of some of the problems in geomechanics — particularly those involving excavations. It is hoped that it will provide an opportunity for the fraternity of geotechnical engineers to appreciate the opening of new frontiers in the use of computers for solving more challenging geotechnical problems.

Geomaterials -- materials whose mechanical behavior depends on the pressure to which they are subjected -- include concrete, soils and rocks. The availability of numerical modeling, which has transformed the study of geomechanics, makes possible the application of numerical methods to the materials and topics treated here. These include brittle and ductile materials, water saturated and partially saturated geomaterials, large and small strains, steady state and transient problems, soil dynamics, strain localization and applications related to natural hazards.

The purpose of this book is to bridge the gap between the traditional Geomechanics and Numerical Geotechnical Modelling with applications in science and practice. Geomechanics is rarely taught within the rigorous context of Continuum Mechanics and Thermodynamics, while when it comes to Numerical Modelling, commercially available finite elements or finite differences software utilize constitutive relationships within the rigorous framework. As a result, young scientists and engineers have to learn the challenging subject of constitutive modelling from a program manual and often end up with using unrealistic models which violate the Laws of Thermodynamics. The book is introductory, by no means does it claim any completeness and state of the art in such a dynamically developing field as numerical and constitutive modelling of soils. The author gives basic understanding of conventional continuum mechanics approaches to constitutive modelling, which can serve as a foundation for exploring more advanced theories. A considerable effort has been invested here into the clarity and brevity of the presentation. A special feature of this book is in exploring thermomechanical consistency of all presented constitutive models in a simple and systematic manner.
