Abstract: Concrete dams are complex structures, the seismic safety of which would not only affect the normal operation of dam itself but also lead to catastrophic effects on a regional scale. In order to design, maintain and manage the concrete dams in a reasonable and effective way, this paper introduces the method of structural fragility analysis. The application of fragility analysis in dams engineering and the technical difficulties are presented. In addition, the developing prospect of the fragility for concrete dams is also put forward.

摘要: 混凝土坝作为复杂的大型水工建筑物,其抗震安全性能不仅影响本身的运行,更涉及下游人民的生命财产安全。为有效地对这类大型复杂结构进行合理设计、维护及管理,减少灾害引起的损失,介绍了结构易损性分析的方法原理,阐述了易损性在大坝工程应用中的重要性和存在的技术难点,并对其发展前景进行了展望。
