Design and practice of foundation pit support under complicated surrounding environmentJiang Bo, Cen Zhengping(Hanjia Design Group Co., Ltd., Hangzhou 310005, China)Abstract: The design and practice of a deep foundation pit with depth of 13.1～14.0m under complicated conditions in Hangzhou was introduced. There are many buildings around the foundation pit and the requirements for surrounding environmental protection are quite strict due to foundation pit excavation. The design process of the foundation pit project was introduced in detail, including the design and construction of diaphragm wall acting as retaining wall and basement exterior wall, and design of the horizontal supporting system. Monitoring results show that the construction combined with the information technology ensures the safety of the surrounding environment in this project.Keywords: deep foundation pit; diaphragm wall; surrounding environment; monitoring
