Abstract: With the trend of quick development of the Beijing urban construction, more and more difficulties for the design and
construction of the pit excavation and retaining structures have been encountered because the deeper and deeper foundation is
used to utilize the underground space. A lot of cases of the foundation pit failures have been reported recently which cause not
only enormous economic losses, but also negative influences. Based on a wide literature review including 141 case studies, the
characteristics of the engineering geology and the main foundation pit excavations and support techniques in Beijing were
summarized and discussed, from which the present technical and application status of the typical foundation pit excavation and
supporting techniques in Beijing can be reflected.
Key words: foundation pit; deep excavation; retaining structure; Beijing area
