| 中文摘要: |
| 边坡的开挖、支挡施工顺序对边坡的稳定性有较大影响.本文通过使用有限元强度折减法对深路堑边坡的不同施工方案数值模拟分析.结果表明，由上至下台阶法开挖，且开挖一级，支护一级的稳定性最高.经过对不同施工方案的对比分析后，达到对施工工序优化的目的. |
| 英文摘要: |
| The excavation of slope,the order of construction of retaining has a greater impact on the stability of slope.This article simulates the deep cut slope excavation of different construction process based on strength reduction FEM.The results show that the method of top-down and step by step supporting excavation has the highest stability.After a comparative study of different post-construction program,we had achieved the purpose of the optimization of construction process. |
