Recommendations on Excavations by Deutsche Gesellschaft für Geotechnik Pdf

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.

Recommendations on Excavations by Deutsche Gesellschaft für Geotechnik Pdf

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 History of the Theory of Structures by Karl-Eugen Kurrer Pdf

This book traces the evolution of theory of structures and strength of materials - the development of the geometrical thinking of the Renaissance to become the fundamental engineering science discipline rooted in classical mechanics. Starting with the strength experiments of Leonardo da Vinci and Galileo, the author examines the emergence of individual structural analysis methods and their formation into theory of structures in the 19th century. For the first time, a book of this kind outlines the development from classical theory of structures to the structural mechanics and computational mechanics of the 20th century. In doing so, the author has managed to bring alive the differences between the players with respect to their engineering and scientific profiles and personalities, and to create an understanding for the social context. Brief insights into common methods of analysis, backed up by historical details, help the reader gain an understanding of the history of structural mechanics from the standpoint of modern engineering practice. A total of 175 brief biographies of important personalities in civil and structural engineering as well as structural mechanics plus an extensive bibliography round off this work.

Fundamentals of Deep Excavations by Chang-Yu Ou Pdf

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.

Deep Excavation by Chang-Yu Ou Pdf

With continued economic development and increasing urbanization, excavations go deeper and become larger in scale, and are sometimes even carried out in difficult soils. These conditions require advanced analysis and design methods and construction technologies. Most books on general foundation engineering introduce the basic analysis and design of excavation, but do not delve into practical considerations. This book examines both theory and practice, from basic to advanced, and discusses the major methods currently in practice around the world. Each chapter also includes problems and their solutions to develop a practical, real-world understanding.

Response of Piled Buildings to the Construction of Deep Excavations by M. Korff,IOS Press Pdf

Deep excavations in densely populated urban areas around the world pose specific challenges due to the increasingly complex conditions in which they are undertaken. The construction of underground car parks, cellar storage areas and major infrastructure in deep excavations helps to preserve the quality of space above ground. Despite the considerable effort that goes into their design and construction, such projects often encounter problems, such as damage to existing structures, delays and cost overruns. This book presents the results of an extensive research project conducted at the University of Cambridge, in cooperation with the Netherlands Centre of Underground Construction (COB) and Deltares, the Dutch Institute for water, subsurface and infrastructure issues. The study gained insight into mechanisms of soil-structure interaction for piled buildings adjacent to deep excavations and resulted in suggestions for designing and monitoring deep excavations in urban areas with soft soil conditions. Monitoring data of the construction of three deep excavations for the North–South metro line in Amsterdam, the Netherlands, have been used to validate the methods described. This book aims to contribute to the reduction of failure costs in the building industry, and in underground construction in particular.

Surface and Underground Excavations, 2nd Edition by Ratan Raj Tatiya Pdf

Surface and Underground Excavations – Methods, Techniques and Equipment (2nd edition) covers the latest technologies and developments in the excavation arena at any locale: surface or underground. In the first few chapters, unit operations are discussed and subsequently, excavation techniques are described for various operations: tunnelling, drifting, raising, sinking, stoping, quarrying, surface mining, liquidation and mass blasting as well as construction of large subsurface excavations such as caverns and underground chambers. The design, planning and development of excavations are treated in a separate chapter. Especially featured are methodologies to select stoping methods through incremental analysis. Furthermore, this edition encompasses comprehensive sections on mining at ‘ultra depths’, mining difficult deposits using non-conventional technologies, mineral inventory evaluation (ore – reserves estimation) and mine closure. Concerns over Occupational Health and Safety (OHS), environment and loss prevention, and sustainable development are also addressed in advocating a solution to succeed within a scenario of global competition and recession. This expanded second edition has been wholly revised, brought fully up-to-date and includes (wherever feasible) the latest trends and best practices, case studies, global surveys and toolkits as well as questions at the end of each chapter. This volume will now be even more appealing to students in earth sciences, geology, and in civil, mining and construction engineering, to practicing engineers and professionals in these disciplines as well as to all with a general or professional interest in surface and underground excavations.
