Finite Element Analysis of Deep and Large Foundation Pit Support Structure in Complex Environment
A deep foundation pit is taken as the research object,and the large-scale finite element software is used to study the excavation,support scheme and construction of the foundation pit.The research results show that the support structure of the foundation pit effectively restrains the uplift of the bottom of the foundation pit,and the settlement of the soil on the outer surface of the foundation pit is concave and the settlement amount is below the warning value;the deformation of the pile body is characterized by a bow-shaped distribution,and the maximum deformation continues to move down with the increase of excavation depth.The simulation results can provide construction experience for similar foundation pit engineering.
