摘　　要：以某高层建筑基坑支护工程为例,利用有限元数值仿真,对比分析了开挖和回填这2种施工方案下钢板桩墙的土压力和水平位移。探讨了这2种施工方案对该工程的适用性,以期为实际工程情况下选择合理的施工方案提供参考。Taking the foundation pit support engineering of a high-rise building as an example and using the finite element numerical simulation,this paper compares and analyzes the soil pressure and horizontal displacement of the steel sheet pile wall under the two construction schemes of excavation and backfill,and probes into the applicability of the two construction schemes to the engineering,so as to provide a reference for selecting a reasonable construction scheme under the actual engineering situation.

关 键 词：钢板桩墙 基坑支护 有限元计算 土压力 位移
