Deep Braced Excavations and Earth Retaining Systems collects the selected publications on deep braced excavation from the Editor. Apart from that, it also contains the basic design theories and principles in analysis of basal heave stability, toe stability, strut forces, retaining wall and ground deformations, auxiliary measures and instrumentation, observation methods and back analysis, etc. Aimed at both theoretical explication and practical application, this book covers a large scope. From basic to advanced, it tries to attain theoretical rigorousness and consistency. Each chapter is followed by problems and solutions so that the book can be readily taught at senior undergraduate and graduate including PhD students. Professors, research students, design engineers as well as staff work for consultation in the field of civil engineering, especially geotechnical engineering can benefit from the book.
Excavation is an essential segment of foundation engineering, for example, in the construction of the foundations or basements of high rise buildings, underground oil tanks, subways or mass rapid transit systems, etc. Though books on general foundation engineering introduce the basic analysis and design of excavations, they are usually too general to cope with the engineering prachce. With economic development and urbanization, excavation goes deeper ancl larger in scale, sometimes it is carried out in difficult soils or complicated built environment. These conditions require advanced analysis, design methods and construction technologies.
The main author has focused on the studies of soil behavior and deep braced excavation problems since working as research fellow in Nanyang Technological University, and has published many reputable journal and conference papers concerning this subject. After joining Chongqing University in 2016, Prof Zhang lectured the postgraduate course \"Excavation and Retaining Systems\" in English to master students from overseas (the photo below). This textbook is mainly based on the lecture notes as well as the scientific journal papers published recently.
仉文崗,Prof Wengang Zhang is full professor of Geotechnical Engineering in School ofCivil Engineering, Chongqing University. He graduated from NanyangTechnological University, Singapore in 2014 and was the recipient of theOverseas High-level Talent (Young Thousand Talented Professor) in 2017.He now serves the school as the Associate Chair, in charge ofinternationalization. His research areas mainly include numerical modelling in deep braced excavation, reliability analysis, and soft computing and big data geotechnical analysis. Prof. Zhang has published 46 papers in international journals as the main author and one book about big data with Springer. He was also the recipient of Computers and Geotechnics 2019 Sloan Outstanding Paper Award. The paper he published in GSF titled \"Multivariate adaptive regression splines and neural network models for prediction of pile drivability\"is also among the top three papers with the highest citations.
