摘要
In order to study the vertical displacement distribution of foundation pit in the process of step-by-step excavation, combined with a foundation pit project, numerical simulation analysis with finite element software was carried in the research. The results show that: in the process of excavation, the maximum settlement of soil outside the pit is 41.4 mm, which is 2.95 parts per thousand of pit excavation depth and conforms to the recommended value in specifications. The maximum vertical displacement of soil at the bottom of foundation pit is in the center of pit. Its value is gradually increasing with the excavation, and the maximum is 60.1 mm, which is 4.32 parts per thousand of foundation pit depth, also, it conforms to the specifications proposed value. The proposed scheme can satisfy the vertical displacement of foundation pit excavation in the construction process.
