摘　　要：采用COMSOL Multiphysics软件搭建了一个基于浅水方程组的二维仿真模型,通过插值函数编辑了计算域内防波堤等地形高度参数,对海啸发生后核电厂区内的洪水演进过程进行了仿真模拟。讨论了不同的最大天文潮位和风暴潮增水、海啸波高组合叠加状态下,核电厂区内的水淹情况和建筑物受到的冲击力,以及防波堤在洪水发展过程中提供的保护作用。计算结果可为核电厂安全级蓄电池、应急柴油发电机组及应急配电装置的布置提供建议。A two-dimensional simulation model based on shallow water equations was built by COMSOL Multiphysics software,and terrain height parameters such as sea wall in the calculation domain were edited through interpolation functions,and the flood evolution process in the nuclear power plant area after the tsunami was simulated.The flooding situation in the nuclear power plant area and the impact of buildings,as well as the protection provided by the breakwater during the flood development process were discussed under different combinations of the maximum astronomical tide level,storm surge and tsunami wave height superimposition.The calculation results can provide suggestions for the arrangement of safety-level batteries,emergency diesel generating sets and emergency power distribution devices in nuclear power plants.
