| Abstract: | 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. |
