- 摘要: This paper is to study the seismic reduction effect of water storage
tank of AP1000 Nuclear Power Plant(NPP) . Using the Arbitrary Lagrangian
Eulerian (ALE) algorithm,coupling fine finite element model of AP1000
shield building for 8 cases of water levels were established to analyze
the dynamic response of water storage tank when the structure was
subjected to the NPP artificial earthquake which agree to RG1. 60
spectrum,parametrically analyze the interaction rule and mechanism of
the accelerations and displacements at different locations of the shield
with water heights,heights of air,height ratios of water levels and
oscillation frequencies of the water tank,and explore the optimal water
level of the water tank for seismic mitigation. Analysis results show
that,on the premise that the water supply satisfy the NPP operating
condition,the minimum dynamic response of the shield building of AP1000
and the best seismic reduction occurs for the case 3,when the height of
water is 8. 8 m and height ratio is 0. 75. - 备注: 新增回溯数据
