| 摘 要： | 在考虑地基与储罐相互作用的情况下，采用有限元法对储罐在水平地震荷载作用下的液体晃动反应进行了分析。结果表明：罐内液体的晃动是长周期运动，并且是多阶振型的组合。从与小体积罐的比较可以看出，大型储液罐的液面晃动不只是以基本振型为主，前几阶振型对液面晃动的贡献也比较显著，并且液面晃动的基本周期比小体积罐的大很多。

| Abstract: | In this paper, sloshing response of liquid in storage tank under horizontal seismic excitation was analysed with finite element method considering interaction between storage tank and flexible soil foundation. The result shows that the liquid sloshing appears as long period and combination of multi-modes. Comparing with small tank, the sloshing in large tank includes not only fundamental mode but also higher modes and its fundamental period is much larger than that of small tank. |
