应用ＦＩＮＡＬ程序对水布垭马崖高边坡进行了数值模拟研究，分别研究了清江水布垭马崖高陡边坡整体三维应力场、位移场特征，考虑了岩体结构总体上硬下软、断层分布等重要特征，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．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，对重要工况还同时进行了ＶＩ度地震作用下的动力作用分析．
FINAL program was used to simulate the high side slope of Shuya Project. The three-dimensional stress field and displacement field characteristics of the high-steep slope of Shuya in Shuibuya Project were studied respectively. Considering that the rock mass structure is hard and soft , Fault distribution and other important features. The change of slope mechanical status after excavation of underground cavern in slope rock mass was studied. Based on the slope cutting is Shuibuya Ma Ya high steep slope one of the important remediation measures, the study carried out a variety of step-by-step excavation conditions under the slope of the effectiveness of quantitative research, the important conditions were also conducted VI Dynamic Analysis of Earthquake.
