The Dingchong reservoir, located at Tongling, Anhui Province in China, was firstly built in October 1959, and then its reinforcement were completed in April 1981. Its dam is an earth dam. Here, according to the practical running status, on the one hand, the seepage FEM is used to calculate and evaluate the seepage behavior of the reservoir dam under different working conditions; on the other hand, the simplified Bishop Method and Swedish circle method are used to get the factor of safety of the reservoir dam under different operating conditions for evaluating the structure behavior. In the light of the results, the seepage behavior is almost normal but the crest elevation of the core wall cannot meet standard requirements, thus great hidden danger exists and the seepage behavior is not safe. During special running period, the factor of safety is relatively small on upstream slope and the structure stability cannot be satisfied, so the security level of the dam is judged to be ill-conditioned, id. C. It is proposed to carry out reinforcement as fast as possible. In reinforcement process, observation facilities should be established in order to grasp exactly running behavior of the dam and to ensure running safety of the project.
