【摘要】 结合某渡槽工程实例,给出渡槽结构抗震设计的计算条件、工况,采用动力有限元法对该渡槽结构的地震反应和动位移进行了计算.计算结果显示,槽内是、否或全部、部分有水,对结构整体的动位移均有一定影响.其中,中槽有水比边槽有水所产生的位移大,且位移分布复杂;河道是否有水对结构位移也有一定的影响.所得结论为渡槽结构的抗震设计提供了依据.更多还原

【Abstract】 The calculating condition and action type are given in the aseismic disign for the aqueduct sturcture. Based on the dynamic finite element method, the earthquake resistance capability and the earthquake displacement of aqueduct structure. Are studied the main conclution is drawn as follows:with or without water, all or part trough is filled with water, will all have influence on the value of dynamic displacement. Especially, middle trough with water may be of much more value in etc. displacement than the sides trough with water.更多还原
