摘　　要：以金沙江上游拟建某水电站高拱坝坝肩为研究对象,应用有限差分程序FLAC-3D对坝肩岩体在天然和荷载后的应力、变形和破坏的发展特征模拟分析,重点分析了坝肩岩体在正常工程荷载下的变形稳定性及坝肩超载特性,得到了坝肩岩体的变形破坏特征及超载安全系数。Taking a high arch dam abutment of Jinshajiang upriver as study object,FLAC-3D numerical simulation was conducted to study stress and deformation-failure features of the rock mass of dam abutment on condition of designed load and overload,to evaluate emphasizely its deformation-stability and overloading capacity,finaly,the conclusion was achieved that there are sufficient safety storage in the dam abutment rock mass and overload safy degree.
