边坡上部基坑开挖数值模拟分析

摘要

In order to solution on the upper part of slope excavation influence on slope stability, using finite element software ansys, the upper slope of different depth of foundation pit excavation numerical simulation and calculation of the slope in the horizontal direction before and after the excavation of the displacement and slope plastic strain differences. The results can provide a reference for the design of slope retaining and protection.%为了解边坡上部基坑开挖对于边坡稳定性的影响，利用有限元软件ansys对边坡上部不同深度的基坑开挖进行了数值模拟，通过计算得到了边坡在开挖前后水平方向的变位以及边坡塑性应变的差异，所得结果可为边坡支挡防护等相关工程的设计提供参考。
