摘要
评述了目前采用的基于坝危害性分类的大坝防洪安全设计标准,讨论了正在发展中的以风险分析为基础的大坝防洪安全设计标准,提出了大坝安全可接受的风险值及大坝失事概率,分析了大坝失事的主要后果及其估算方法,为风险分析在大坝防洪安全评价中的应用创造条件。
The basic criteria applied at present for the assessment of hydrological safety of dams under designing and operation are reviewed, which are based on dam hazard classification. The new criteria based on risk analysis are discussed. The society acceptable risk levels for dam safety and the acceptable probability of dam failure are presented respectively. The hazard losses caused by dam failure and the evaluation methods are described.
