Abstract：
Based on the deep foundation pit construction of a high-rise building as the research background, according to the foundation pit support programs, monitoring programs and other information, combined with monitoring data, focusing on analysis of the deformation characteristics of the retaining pile foundation excavation stage. The results show that: During the construction of the foundation pit retaining pile accumulated deep horizontal displacement occurs mainly in the earthwork excavation stage; With the excavation depth increases and the supports of concrete pouring, retaining pile deformation curve by forward type gradually changes to bow, accumulated deep horizontal displacement increases, the maximum cumulative displacement position move downstream; With increasing measurement times, pile first support position cumulative horizontal displacement of the deep value smaller, and the second and the third support and bottom position of deformation values show the volatility of trend growth, retaining pile deformation of key parts in pile third support position. The research results have certain reference value for the design and construction of other similar excavation works.
