The biggest problem for a shallow foundation, just as for any other type of foundation, is a failure due to an overestimation of the bearing capacity. This means that the correct prediction of the bearing capacity of the foundation is often the most important part of the design of a civil structure. That is why the publication by Prandtl in 1920 about the hardness of a plastic body, was a major step in solving the bearing capacity of shallow foundations, although it is well possible that he never realised this, because his solution was not made for civil engineering purposes, but for mechanical purposes. Over the last 100 years, a lot of extensions have been made, for example with inclination factors and shape factors. Also many laboratory experiments have been done and numerical calculations have been made. Some even try to extrapolate the failure mechanism for shallow foundations to the failure mechanism around the tip of a pile. All this scientific work leads back to the first publication by Ludwig Prandtl in 1920. This book, “100 Years of Prandtl’s Wedge”, is intended for all those who are interested in these fundamentals of foundation engineering and their history. The Appendices include a copy of Prandtl’s Über die Härte plastischer Körper and of Reissner’s publication of 1924, Zum Erddruckproblem.

Model Uncertainties in Foundation Design is unique in the compilation of the largest and the most diverse load test databases to date, covering many foundation types (shallow foundations, spudcans, driven piles, drilled shafts, rock sockets and helical piles) and a wide range of ground conditions (soil to soft rock). All databases with names prefixed by NUS are available upon request. This book presents a comprehensive evaluation of the model factor mean (bias) and coefficient of variation (COV) for ultimate and serviceability limit state based on these databases. These statistics can be used directly for AASHTO LRFD calibration. Besides load test databases, performance databases for other geo-structures and their model factor statistics are provided. Based on this extensive literature survey, a practical three-tier scheme for classifying the model uncertainty of geo-structures according to the model factor mean and COV is proposed. This empirically grounded scheme can underpin the calibration of resistance factors as a function of the degree of understanding – a concept already adopted in the Canadian Highway Bridge Design Code and being considered for the new draft for Eurocode 7 Part 1 (EN 1997-1:202x). The helical pile research in Chapter 7 was recognised by the 2020 ASCE Norman Medal.

Methods for improving ground and soil have undergone significant developments in recent years, particularly in terms of application and usage, and many innovative techniques have been introduced. However, it is of significance that in many areas the design process still lacks a theoretical framework. The papers included in this volume, written by international authors, deal with a cross-section of problems faced by many practising engineers and provide advice and guidance on how these problems can be dealt with in a practical manner.

This series, under the editorship of Professor H.J. Zwart, will deal with all topics within this field, such as: micro structures, large scale tectonics, experimental structural geology, fabrics, rock mechanics, and modelling in structural geology. The aim is to publish advanced level reference books to provide state-of-the-art reviews of these and other aspects of structural geology. This series will be of value to researchers and professionals in structural geology, rock mechanics, petroleum geology and tectonophysics.This first volume in the series deals with the mechanics of tectonic faulting and its central theme is the formation of faults in the tectonic stress field and the interaction between faults and stresses. The author, Dr. G. Mandl, was one of the top research people with Shell International Research. Part I of the book deals with the mechanical genesis of general fault features, such as fault shape and antithetic, precursory and secondary faulting and elaborates on these more general aspects within the context of specific tectono-mechanical models for extensional faulting and thrusting. Besides critical reviews, Part I contains a number of new or hitherto unpublished results, in particular on model experiments and numerical analyses. The central chapter of Part II presents a full introduction into mechanical theory and rock plasticity - the theory most adequate to tectonic faulting and therefore forming the backbone of the book. Besides presentations of basic concepts of stress and strain, special chapters are devoted to poro-elasticity and fluid flow through porous rocks. This branch of geomechanics requires a multidisciplinary approach that combines continuum mechanics, rock mechanics and structural geology, and applies theoretical, numerical and experimental methods, together with the study of field cases. The book has evolved from such multidisciplinary research and is written for structural geologists, petroleum geologists, engineering geologists, rock engineers and geophysicists whose work demands a similar approach. In addition, the book is intended to encourage mechanical engineers and even mathematicians to enter the fascinating and in parts still untilled fields of tectono-mechanical processes in the Earth's crust. The book is richly illustrated by drawings, photographs and reproductions of seismic records.
