| 摘 要： | 清江水布垭水电站是清江上游拟建的一个特大型水电工程，马崖高边坡位于水布垭峡谷出口右侧，总体地质结构具上硬下软特征，电站导流洞及尾水洞将从马崖高陡边坡坡脚穿出，地下开挖主要在软岩层中。应用FINAL及ROCKY程序对水布垭马崖高陡边坡岩体地下开挖进行数值模拟，研究了边坡岩体内进行地下洞室开挖后边坡力学状态的改变及洞室岩体（含岩柱）的稳定性，基于削坡是水布垭马崖高陡边坡的重要整治措施之一，研究中进行了各种分步开挖工况下的削坡有效性定量研究，重要工况还同时进行了VI度地震作用下的动力作用分析。

| Abstract: | D numerical simulation of underground excavation in high rock slope with software Rocky was carried out for study of Maya rock slope engineering related to Shuibuya hydroelect power project. The numerical simulation of mechanical situation and rock pillar stability of tunnel engineering in the slope and slope cuting measures for the stability control are illustrated in detail. These studies also consist of earthquake dynamic simulation of slope engineering in practice. The numerical simulation result shows that the study is reasonable and practical. |
