摘　　要：模拟基坑开挖过程,由应力场变化方面入手分析开挖面以下粘性土体残余强度和静止土压力的规律性,以期确定土体开挖卸荷的影响深度。By simulating the excavation course of foundation pits and starting with the change of stress field, the regularities of remanent strength and static earth pressure of viscous soil mass under excavated plane are analyzed so that the influence depth due to soil mass excavation unloading may be determined.

关 键 词：卸荷 残余强度 应力场 静止土压力 影响深度
