The aim of these recommendations is to harmonize and further develop the methods, according to which excavations are prepared, calculated and carried out. Since 1980, these have been drawn up by the working group "Excavations" at the German Geotechnical Society (Deutsche Gesellschaft für Geotechnik DGGT) and are similar to a set of standards. They help to simplify analysis of excavation enclosures, to unify load approaches and analysis procedures, to guarantee the stability and serviceability of the excavation structure and its individual components, and to find out an economic design of the excavation structure. For this new edition, all recommendations have been reworked in accordance with EN 1997-1 (Eurocode 7) and DIN 1054-1. In addition, new recommendations on the use of the modulus of subgrade reaction method and the finite element method (FEM), as well as a new chapter on excavations in soft soils, have been added.
Since 1949 the "Committee for Waterfront Structures" has operated on honorary base as a committee of the Society for Harbour Engineering (HTG), Hamburg, and since 1951 also as working group of the German Society for Geotechnics (DGGT), Essen. Its full designation reads "Committee for Simplification an Standardization of Calculation and Construction of Waterfront Structures", which also outlines its goals. Following on from the previous joint publications, this new edition of EAU 2004 contains the safety concept with partial safety factors in accordance with the Eurocodes or the European prestandards as well as with the new edition of the corresponding German standard, partially differing on account of practice experiences. The recommendations continue to satisfy the requirements for international acknowledgement and application with regard to planning, design tendering, the awarding of contracts, building and building supervision. Further, the inspection and accounting procedures for harbour and waterway constructions are given from uniform points of view.
Civil Engineering has recently seen enormous progress in the core field of the construction of deep foundations. This book is the result of the International Workshop on Recent Advances in Deep Foundations (IWDPF07), which was held in Yokosuka, Japan from the 1st to the 2nd of February, 2007. Topics under discussion in this book include recent research achievements and case histories; and current advances in the applied aspects of deep foundations, such as reliability-based design, field tests and experimental field work. The book also features the latest numerical simulation methods and theoretical findings. There are nine keynote lectures, focusing on foundation engineering in different parts of the world, and thirty-three state-of-the-art papers from eminent international experts. The techniques covered include sheet piles, piles, pile-ground improvement and ground improvement, while dynamic aspects and design are also discussed.. This book is intended for an international audience of researchers and professionals in soil and foundation engineering.
