Simulation Study on Force and Deformation of Inclined Pile Supporting System in Foundation Pit Engineering
In order to fully explore the applicability of inclined pile support system in building foundation pit support,and ensure the reinforcement effect of foundation pit enclosure.Combined with the practice of foundation pit support of Huijin Building project in Liupanshui City,this paper simulates the stress and deformation of inclined pile support system in the process of foundation pit excavation by using PLAXIS3D numerical model.The results show that the total displacement of soil is 29.6mm,and the x,y and z displacement are 23.7,4.9and 17.8mm respectively.The stability of foundation pit meets the standard requirements.The larger the excavation depth of foundation pit,the larger the lateral displacement of inclined pile and vertical pile,and their maximum displacement is 6.96and 8.76mm respectively,which does not exceed the allowable value of the code,and fully meets the standard requirements.The simulation analysis,the feasibility of the inclined pile supporting structure in the foundation pit support is verified effectively.
