| 摘 要： | 用强度折减有限元法对边坡重力作用下开挖前后的稳定性进行了较为全面的对比分析研究。采用Drucker-Prager屈服准则,运用ANSYS软件作为计算分析工具,对二塘沟水库右岸天然边坡开挖前后的稳定性进行了模拟计算,并分析了天然边坡开挖前后的应力-应变状态,为边坡的治理决策提供了依据。

| Abstract: | In this paper,the study was conducted to comparalively analyze the stability of natural slope brfore and after excavation slope by use of the strength reduction FEM,based on Drucker-Prager yield criterion and by use of ANSYS software as calculation and analysis tools,to make a concrete analysis of all about the slope excavated and the analoy computation was carried out on the stability of right abutment of Ertang valley reservoir before and after excavation slope,then the stress and strain siluations of the natural slope before and after excavation slope were analyzed to provide a basis for controlling the slopes. |
