摘　　要：结合水电站2种不同滑动破坏模式,基于三维极限平衡法用分析软件对边坡稳定进行分析计算。针对边坡变形体,分析2种滑动模式,分别拟定3种计算工况,考虑未支护和在锚索支护情况下进行安全系数的计算,结果表明边坡稳定性均能满足施工期及运行期的要求,在锚索支护下边坡的安全系数有一定的提高,可以为工程实践提供依据。Combined with two different sliding failure modes of hydropower station, the slope stability is analyzed and calculated by using analysis software based on three-dimensional limit equilibrium method. Aiming at the slope deformation body, two kinds of sliding modes are analyzed, three calculation working conditions are drawn up respectively, and the safety factor is calculated without support and in the case of anchor cable support. The results show that the stability of the slope can meet the requirements of construction and operation, and the safety factor of the slope under anchor cable support is improved to a certain extent, which can provide a basis for engineering practice.
