| Abstract: | In consideration of topographical and geological conditions of Jinping arch dam,and characteristics of joint fissures,the stability of the dam as well as the working condition are studied with 3D non-liner Finite Element Method.The deformation and damage of abutment is analyzed by way of safety coefficient methods of integral overload.It shows that the safety coefficient of integral overload is 4.2. |
| Keywords: | arch dam abutment stability joint and fissure rock mass Finite Element Method over-load characteristics |
