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 fur 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.

With the issue of these recommendations, which have the character of a standard, the "Building Excavations" working group of the German Geotechnics Association (DGGT) aims to provide assistance with the design and structural calculation of excavation support works. The introduction of the Eurocodes for building control purposes made necessary a revision of the previous edition of the recommendations to comply with the requirements of DIN EN 1997-1:2009 together with the national annex DIN 1997-1/NA:2010-12 and the supplementary regulations of DIN 1054:2010-12. All recommendations were thoroughly checked, revised where necessary and adapted to new knowledge. Chapter 10 "Building excavations in water" was substantially revised. Due to the progress of development of measurement instruments and the more stringent requirements, Chapter 14 "Instrumentation for the monitoring and supervision of building excavation support works" was formulated completely anew. The recommendations of the working group "Building Excavations" should be of assistance, - to simplify the design and structural calculation of excavation support works, - to harmonise loading assumptions and calculation procedures, - to ensure the structural stability of excavation support works and their individual elements and - to improve the cost-effectiveness of excavation support works.

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 for excavations at the German Society for Geotechnics (Deutsche Gesellschaft für Geotechnik) under the name EAB and are similar to a set of standards. All the main software programs in Germany are based on these recommendations. The recommendations help in designing and calculating excavation constructions, unifying approaches to loads and methods of calculation. Since they are based on an approved global safety concept, following these recommendations ensures the stability and usability of excavations and their individual components. Furthermore, they help to improve the profitability of excavation constructions. The result is a work of major importance for all experts concerned with the planning and calculation of excavations.

Excavation is an important segment of foundation engineering (e.g., in the construction of the foundations or basements of high-rise buildings, underground oil tanks, or subways). However, the excavation knowledge introduced in most books on foundation engineering is too simple to handle actual excavation analysis and design. Moreover, with economic development and urbanization, excavations go deeper and are larger in scale. These conditions require elaborate analysis, design methods and construction technologies. This book is aimed at both theoretical explication and practical application. From basic to advanced, this book attempts to achieve theoretical rigor and consistency. Each chapter is followed by a problem set so that the book can be readily taught at senior undergraduate and graduate levels. The solution to the problems at the end of the chapters can be found on the website (http://www.ct.ntust.edu.tw/ou/). On the other hand, the analysis methods introduced in the book can be used in actual analysis and design as they contain the most up-to-date knowledge. Therefore, this book is suitable for teachers who teach foundation engineering and/or deep excavation courses and engineers who are engaged in excavation analysis and design.

The book reviews recent developments and research results on excavations and foundations found in and on soft soil deposits. It gives an overview of the material properties of soft soils and offers new foundation improvement techniques in road and railways. It also examines different types of foundations and stabilization methods. The book will serve both practicing and research engineers in the field of geotechnical engineering.

&Quot;This book assembles the practical rules and details for the efficient and economical execution of deep excavations. It draws together a wealth of experience of both design and construction from published work and the lifetime practice of the author. This second edition is extensively revised to include changes in design emphasis including those due to Eurocode 7 and descriptions of the latest equipment, construction techniques and geotechnical processes. Additional details include those of the latest piling and diaphragm wall equipment and innovations in top-down construction applied to basements and cut-and-cover works. The section on caissons has been expanded to include design methods."--BOOK JACKET.

The relationship between archaeology and conservation has long been complex and, at times, challenging. Archaeologists are often seen as interested principally in excavation and research, while conservators are concerned mainly with stabilization and the prevention of deterioration. Yet it is often initial conservation in the field that determines the long-term survival and intelligibility of both moveable artifacts and fixed architectural features. This user-friendly guide to conservation practices on archaeological excavations covers both structures and artifacts, starting from the moment when they are uncovered. Individual chapters discuss excavation and conservation, environmental and soil issues, deterioration, identification and condition assessment, detachment and removal, initial cleaning, coverings and shelters, packing, and documentation. There are also eight appendixes. Geared primarily for professionals engaged in the physical practice of excavation, this book will also interest archaeologists, archaeological conservators, site managers, conservation scientists, museum curators, and students of archaeology and conservation.

The safe and economical construction of tunnels, mines, and other subterranean works depends on the correct choice of support systems to ensure that the excavations are stable. These support systems should be matched to the characterstics of the rock mass and the excavation techniques adopted. Establishing the support requirements, designing support systems and installing these correctly are essential elements in safe underground construction. This is a comprehensive and practical work which also gives access to user-friendly computer programmes which enable the investigation and design of support techniques. Details on how to obtain this software are also included in the book.
