中文摘要：
边坡开挖将对边坡的稳定性产生不利影响，加锚支护则可以提高边坡稳定性。基于锚固岩体的流变模型，采用弹塑性有限元法对边坡开挖加固进行了数值模拟，分析了开挖边坡的稳定性，并对初拟的边挖边锚的施工程序的合理性进行了评价，提出了若干对工程建设具有一定指导意义的建议。
英文摘要：
The excavation will do harm to the stability of side slope of hydropower plant. It＇s a good way to reinforce rock mass to improve the stability of the side slope. Based on an elastoplastic constitutive model of rock mass reinforced with rock bolts and cables, numerical simulations are performed by elastoplastic FEM to evaluate the stability of side slope during slope excavation, reinforcement and under Seismic loading, and to evaluate the effectiveness of a suggested construction procedure of anchoring immediately after excavation. Finally, several suggestions that may be helpful to the stability of side slope, are presented.
