The Stability Of Foundation Pit Supporting Structure And The Analysis Of Displacement In Era Of Emperor

Take the sewage treatment plant of SHI DAI DI JING foundation pit in BEI JING as an engineering background to study the pile anchor supporting structure in deep foundation pit, correlation displacement data and excavation or support progress of china satellite communications building foundation pit engineering, at the same time, by numerical simulation method, the stress and deformation characteristics of pile anchor supporting structure applied in deep foundation pit were studied. Research has made the following main results and conclusion:(1) The horizontal displacement of pile body and the pile top is closely related with excavation or support condition, the pile body displacement shows two different convergence situation.(2) Through numerical simulation analysis of the south wall of foundation pit, internal force diagram of pile anchor structure changes with the length and angle of anchor. And the pile anchor structure internal force and soil displacement change with excavation or support situation. From the cloud picture and the curve extracted from corresponding node value, the development situation of numerical simulation and actual situation are basically consistent.
