A deep foundation pit project adopts pile anchor support system.In order to ensure the reliability of the support scheme,the researchers used BIM structure analysis software to establish a finite element model of foundation pit and support measures,and carried out four stages of excavation in a virtual way until the base is reached.Monitoring points of soil and pile are set on the virtual model to measure the horizontal displacement of soil,vertical displacement of soil,horizontal displacement of retaining pile and bending moment change of retaining pile.Then comparing the numerical simulation results and the sensor measurement results proves the feasibility of the foundation pit construction scheme.
