摘　　要：以一具体工程为例,采用数值分析的方法,模拟研究基坑开挖过程中预应力锚杆与土钉墙复合支护结构的受力性状、工作性能和作用机理,并在数值分析中利用强度折减法分析基坑开挖后的稳定性。The stress characters, working behaviors and action mechanism of composite structure supported with pre - stressed anchor and soil - nailing wall was simulated by numerical analysis method during the course of excavation. Strength reduction method was used to analyze the stability of the foundation after excavation.

关 键 词：预应力锚杆 土钉墙 支护结构 强度折减法
