In order to compare and select different foundation pit support schemes and study the deformation control effect of foundation pit under different support parameters,based on a building foundation pit project,this paper compares and selects three primary support schemes(double-row pile support,underground continuous wall,single-row pile+anchor support)through Analytic Hierarchy Process and fuzzy comprehensive evaluation method,and analyzes the control effect of different pile lengths of double-row piles on foundation pit deformation based on finite element simulation.The results show that the double-row pile support scheme is the optimal support scheme;increasing pile length appropriately can effectively reduce the horizontal displacement of the pile body.
