In order to study the foundation pit supporting structure displacement of the change rule and different parameters on the transverse displacement effect of pile. My research based on supporting structure engineering of Shenyang Washington. We use the software ADINA as a research tools to establish a finite element model. We simulated and analyzed the displacement with and without anchor. Results show that adding anchor supporting played a very good supporting effect, and the simulation results and actual test results compared and analyzed proved reasonable and simulation design scheme was feasible, this excavation has some guidance for the engineering and a certain reference for similar deep foundation pit bracing.
