Stability Analysis of Foundation and Abutment of Arch Dam Based on ANSYS

According to the topographical,geological features,the distribution of weak structure of the arch dam,a three-dimensional numerical model of arch dam under the natural foundation conditions is established by ANSYS software.Using overloaded method,which can analyze and calculate the displacement of the dam and abutment,the relative displacement of weak structure plane,and the failure pattern and process of the dam and abutment just as in the model test,the overload coefficient of overall stability is obtained.It can evaluate the safety of arch dam.The results have provided the important scientific basis for the design,construction and reinforcement of the project.
