Support Design and Practice of a Deep Foundation Pit Project in Shanghai Area

Taking a deep foundation pit support engineering in Putuo District,Shanghai Zhenda Road as an example,giving full consideration to the characteristics of this project,combined with safety,economy and other aspects,to determine the bored pile with supporting a concrete form of the retaining,the shallow parts of the gravity retaining.This paper introduces the support scheme selection,design and calculation,and provides relevant information monitoring results,practice shows that the support effect is good,and provides some reference for the later similar projects.
