Fundamentals of Deep 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.

Chang-Yu Ou, Ph.D., is a Chair Professor of the Department of Civil and Construction Engineering at the National Taiwan University of Science and Technology, Taipei, Taiwan. He received his doctoral degrees from Stanford University in 1987. He is the chair of the ATC6 of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE). He was the Dean of the College of Engineering at the National Taiwan University of Science and Technology and the President of the Taiwan Geotechnical Society.

His areas of interest are deep excavations, soil behavior, soft ground tunneling, and ground improvement. He has published more than 200 journal and conference papers. He has received three outstanding research awards and received a research fellow award from the National Science Council of Taiwan. He was also awarded many journal paper awards. In addition to publishing the book Deep Excavation: Theory and Practice with Taylor & Francis, he has also published three deep excavation books in the Chinese language. Because of his outstanding research results, he has participated in many large-scale projects related to deep excavations as a reviewer, designer, or analyst.
