摘　　要：CAP1400屏蔽厂房屋顶PCS水箱为一坡底的环状水箱，而非传统的方形水箱或圆形水箱，无法直接应用规范公式进行水箱结构设计。本文采用ANSYS软件．建立CAP1400屏蔽厂房屋顶PCS^K箱有限元模型（水采用流体单元Fluid80进行模拟），进行流固耦合分析，计算了PCS水箱水晃动的动力特性（如水晃动主频及参与质量），并与基于经验公式的等效计算结果进行了比较；最后，对长周期地震作用下的水晃动效应进行了分析评估。PCS tank on CAP1400 Shield Building roof is an annulus water storage tank with sloping bottom instead of a rectangular or cylindrical tank, so some code formulas cannot be applicable for de- signing PCS tank structure directly. In this paper, a FE model of PCS tank on CAP1400 Shield Building roof is created, and the water is simulated by Fluid80 element. Based on this model, the fluid-structure interaction analysis is performed to calculate the dynamic characteristic of water sloshing in PCS tank, and the corresponding results are compared with equivalent calculation by experienced formulas. Finally, the water sloshing analysis for long period earthquake is also performed.
