摘要

一般情况下矩形贮液结构通过底板直接坐落在地基上，有必要在考虑地基效应的基础上研究其动力特性。定义了微幅晃动波高限值，建立了矩形贮液结构的简化模型。采用人工边界模拟地基效应，建立了有限元计算模型，对比了两类模型对应的晃动波高以验证简化模型的合理性，基于势流理论在微幅晃动范围内研究了不同边界条件、不同地震波和不同地震加速度幅值下矩形贮液结构的动力响应。结果表明，两类模型得到的晃动波高趋势一致，且最大晃动波高相差较小。在微幅晃动范围，液体最大晃动波高和地震加速度幅值成线性关系，考虑土-结构相互作用后，壁板水平位移、壁板有效应力和液体晃动压力有较大程度的的减小，而地基效应对液体晃动波高影响很小。

Abstract

A rectangular liquid-storage structure is often located on a foundation through bottom plates,it is necessary to study its dynamic characteristics considering the foundation effect.Here,the limit height of small amplitude sloshing was defined,the simplified model of the rectangular liquid storage structure was established.Using artificial boundaries to simulate foundation effect,the finite element calculation model was established.Sloshing heights corresponding to two kinds of models were compared to verify the rationality of the simplified model.Based on the potential flow theory,the dynamic responses of the rectangular liquid-storage structure under different boundary conditions,different seismic waves and different seismic acceleration amplitudes were studied.The results showed that the sloshing height trends of the two kinds of models are consistent,and the difference of the maximum sloshing heights is small; in the range of small amplitude sloshing,there is a linear relationship between the maximum sloshing height and the amplitude of earthquake acceleration; after considering soil-structure interaction,the tank wall horizontal displacement,tank wall effective stress and liquid sloshing pressure have a larger level of reduction,but the foundation effect has little influence on liquid sloshing height.
