| 摘 要： | 运用有限元强度折减法对深圳某深基坑开挖进行了有限元数值模拟，研究了基坑开挖后稳定性系数、变形与单桩、抗滑桩结合不同排数锚索支护方案的关系，探讨了桩锚支护时不同锚索预应力与稳定性系数、变形和桩身内力的关系，从而确定基坑边坡的最优设计方案。

| Abstract: | The paper makes finite numerical simulation on a deep ditch excavation in Shenzhen by using strength reduction FEM, it analyzes stability of the foundation, and relationship between deformation and combining of single pile and anti-slide pile with different anchor number supporting schemes, it discusses relationship between prestress and stability of different anchors, as well as deformation and internal force of the pile when using the pile anchor supporting, so as to make the best designing scheme of foundation slide slope. |
