| 英文摘要 | In order to explore the integral safety degree, probable failure type and failure mechanism of high dam, the combination of overloading and strength reduction method is adopted to simulate the progressive failure and potential destabilization pattern of dam-foundation system. By using finite element method, the overloading of dam-foundation system is carried out firstly and then keeping the load combination unchanged, by reducing rock material strength parameters step by step. The general safety degree of dam-foundation system is obtained. The method mentioned above has been used in Guangzhao roller compacted concrete (RCC) gravity dam, the finite element calculation results show that integrated safety degree of GuangZhao RCC Gravity Dam is greater than 3.0 and the safety degree of the dam foundation surface which is the weakest position of the dam-foundation system is greater than 2.0. The research results indicate that the safety coefficient can satisfy the engineering requirement and the method is efficient and accurate in high dam safety evaluation. |
