【摘要】 渡槽主要特点是上部槽内有巨大水体,当地震波沿着横向作用时,上部巨大的水体不但产生大的惯性力,还存在水体晃动影响。在渡槽减隔震研究中,减隔震装置有滤波作用,而目前没有关于槽内水体晃动及其动力响应与减隔震装置滤波效应之间关系的相关研究。本文首先分析了弹性支撑滤波作用下受不同频率简谐波激励的槽-水耦合体振动特点,其次观察了地震激励下渡槽采用不同减隔震装置时横向动力响应,并结合滤波作用下槽-水耦合体振动特点进行成因说明。更多还原

【Abstract】 A key feature of aqueduct is that if a transversal seismic wave impacts it,a great inertia force and sloshing will be generated by the huge volume of water inside it.A seismic isolation device commonly has filter function.The relationship between the dynamic responses of water-duct coupled components and such a filter function,however,was not studied.This paper presents a study on such dynamic responses under stimulation of sine waves of different circular frequencies.Transversal seismic responses of the coupled components are observed and illustrated,and the filter function is examined.更多还原
