Abstract:
Concrete slope protection and concrete anti-seepage wall are technically mature when used in the seepage reinforcement of earth dam. However, the comprehensive evaluation of its actual anti-seepage effect lacks the computational basis. In this paper, finite element method has been used to compute the characteristics of the dam structure in the Changli Reservoir before and after the reinforcement. The results showed that the effect of the anti-seepage system with the concrete slope protection and concrete anti-seepage wall has good effect and the seepage condition of the dam body and foundation is improved. After the reinforcement, the seepage slope and seepage discharge of each area decreased significantly and met the standard requirements.
