Book Description
This book presents simplified and advanced probabilistic analyses of shallow foundations. In the simplified probabilistic analysis the uncertain parameters are modelled by random variables defined by their probability density functions. In other words, the soil is considered homogeneous. However, in the advanced probabilistic analysis, the uncertain parameters are modelled by random fields characterized not only by their probability density functions, but also by their autocorrelation functions. This allows studying the effect of the soil spatial variability on the behaviour of shallow foundations.

Book Description
Cette thèse présente des approches simplifiées et avancées pour l’analyse probabiliste des fondations superficielles. Dans l'analyse probabiliste simplifiée, les paramètres incertains sont modélisés par des variables aléatoires. Pour une fondation soumise à un chargement incliné, les résultats numériques basés sur la méthode des surfaces de réponse (RSM) et la méthode des surfaces de réponse stochastiques (CSRSM) ont permis d'identifier les zones de prédominance des modes de rupture à l’état limite ultime et à l’état limite de service. D'autre part, une procédure efficace a été proposée pour augmenter le nombre des sorties probabilistes de l’approche Subset Simulation (SS) sans appels supplémentaires au modèle déterministe. Dans cette procédure, l'approche SS a été combinée avec la méthode CSRSM. Dans l'analyse probabiliste avancée, les paramètres incertains du sol sont modélisés par des champs aléatoires pour prendre en compte la variabilité spatiale des propriétés du sol. Dans ce cas, la méthode de simulation de Monte Carlo (MCS) est généralement utilisée et seuls les moments statistiques de la réponse sont étudiés en raison du grand nombre d'appels au modèle déterministe. Dans cette thèse, l'approche SS a d’abord été utilisée comme une méthode alternative à la méthode MCS pour calculer la probabilité de ruine. Ceci a conduit à une réduction significative du nombre d'appels au modèle déterministe. Ensuite, une approche plus efficace nommée improved Subset Simulation (iSS) a été développée pour réduire encore une fois le nombre d'appels au modèle déterministe. L'utilisation de l’iSS a réduit le nombre d'appels au modèle déterministe d'environ 50% par rapport à l'approche SS.

Book Description
Following the popularity of the previous edition, Shallow Foundations: Bearing Capacity and Settlement, Third Edition, covers all the latest developments and approaches to shallow foundation engineering. In response to the high demand, it provides updated data and revised theories on the ultimate and allowable bearing capacities of shallow foundations. Additionally, it features the most recent developments regarding eccentric and inclined loading, the use of stone columns, settlement computations, and more. Example cases have been provided throughout each chapter to illustrate the theories presented.

Book Description
Analysis, Design and Construction of Foundations outlines methods for analysis and design of the construction of shallow and deep foundations with particular reference to case studies in Hong Kong and China, as well as a discussion of the methods used in other countries. It introduces the main approaches used by geotechnical and structural engineers, and the precautions required for planning, design and construction of foundation structures. Some computational methods and computer programmes are reviewed to provide tools for performing a more realistic analysis of foundation systems. The authors examine in depth the methods used for constructing shallow foundations, deep foundations, excavation and lateral support systems, slope stability analysis and construction, and ground monitoring for proper site management. Some new and innovative foundation construction methods are also introduced. It is illustrated with case studies of failures and defects from actual construction projects. Some advanced and modern theories are also covered in this book. This book is more targeted towards the understanding of the basic behavior and the actual construction of many geotechnical works, and this book is not dedicated to any design code or specification, though Euro codes and Hong Kong code are also used in this book for illustration. It is ideal for consulting geotechnical engineers, undergraduate and postgraduate students.

Book Description
One-of-a-kind coverage on the fundamentals of foundation analysis and design Analysis and Design of Shallow and Deep Foundations is a significant new resource to the engineering principles used in the analysis and design of both shallow and deep, load-bearing foundations for a variety of building and structural types. Its unique presentation focuses on new developments in computer-aided analysis and soil-structure interaction, including foundations as deformable bodies. Written by the world's leading foundation engineers, Analysis and Design of Shallow and Deep Foundations covers everything from soil investigations and loading analysis to major types of foundations and construction methods. It also features: * Coverage on computer-assisted analytical methods, balanced with standard methods such as site visits and the role of engineering geology * Methods for computing the capacity and settlement of both shallow and deep foundations * Field-testing methods and sample case studies, including projects where foundations have failed, supported with analyses of the failure * CD-ROM containing demonstration versions of analytical geotechnical software from Ensoft, Inc. tailored for use by students in the classroom
