摘要：
In this paper, taking one domestic RCC (Roller Compacted Concrete) gravity dam as an example. An evaluation method base on distribution of tensile stress, the sliding stability, the material strength, interpenetrate plastic zone and the ratio of demand-capacity with the overstress cumulative time is proposed for analyzing the seismic safety of the dam. The methodology proposed is effectively and comprehensively. The result showed that the structure of dam may be partially cracked and subjected to low or moderate damage. © 2020, Nanjing Univ. of Aeronautics an Astronautics. All right reserved.
