    Abstract
  • Due to the insufficient of lateral resistance in the passive area, the deformation and displacement of the supporting pile and wall increase with the deepening of the foundation pit excavation, so it is necessary to strengthen the control of the deformation and displacement of the supporting pile and wall by strengthening the soil in the passive area to improve the embedding condition of the soft soil at the bottom of the pit. Combined with practical engineering of supporting pile, a fitting method of the optimal reinforcement depth and width of cantilever support foundation pit bottom was provided. Numerical simulation of the strengthening effect of different depth and width were analyzed, and the passive area soil consolidation mechanism and optimization were further studied, which provides practical reference in similar project.
