摘　　要：根据建立的多裂隙岩体弹塑性断裂损伤耦合力学模型,通过三维有限元计算,系统地研究了小湾水电站拱坝坝肩岩体的稳定性,得到了坝肩岩体应力和变形的定量结果,在此基础上,提出了技术经济较优的坝肩加固方案。Based on the fracture-damage coupled constitutive model of jointed rock mass,3-D FEM analysis on stability of Xiaowan arch dam abutment is proceeded. The distribution of stress and deformation of abutment and dam is obtained. Furthermore,the preferred reinforcement schemes of abutment are suggested according to the technical and economic feasibility.
