摘要

Based on FLAC^(3D) finite difference soft armor, the arching effect of passive soil arching in front of cantilever pile was studied, and the influence of the change of pile depth direction and the soil strength of different embedded sections on the passive soil arching effect in front of pile was analyzed.The results show that the passive soil arching effect can occur in the soil of two adjacent piles, and it decreases along the depth of the pile. However, when the strength of the embedded soil is small, the pile displacement is too large, and the passive soil arching effect cannot occur in the surface soil, but can occur in the deeper soil.
