The Example Analysis for Design and Construction of Deep Excavation Project in Beijing

In recent years,with the rapid development of economy and city construction in our country,especially of large and medium-sized cities in China,the top and tall building has been developing rapidly,and many high-rise building deep basement,so the design and construction of deep foundation pit supporting is particularly important.Based on a deep excavation project in Beijing,from design,construction and monitoring of the foundation pit engineering in three aspects,this paper summarizes the region experiences and lessons in the process of design and construction of foundation pit,serve as a reference for similar engineering design and construction.
