| Abstract: | A numerical simulation on Xiaowan arch dam under reinforcement was performed using Three Dimensional Non-linear Finite Element Method. The displacements and stresses of the dam were analyzed and the arch dam uplift was researched. At last the overloading capacity of Xiaowan arch dam was calculated. |
