【摘要】 本文简述某渡槽工程结构布置 ,结合抗震设计对计算条件、工况进行了分析 ,采用动力有限元法程序对该渡槽结构进行了计算。结果表明 ,渡槽内是否有水 ,以及部分槽道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。所有结论为渡槽结构的抗震设计提供了依据更多还原

【Abstract】 The engineering structure plan of an aqueduct example is brief introduced in this paper. For the anti-seismic design, the calculating conditions and action type are analysed. Based on dynamic finite element method, the earthquake resistance capability and the earthquake displacement of the aqueduct structure are studied. Some significative conclusions are educed. The maim conclusion is as follows: the conditions with water whether or not, or with part water influence the value of dynamic displacements, especially the middle tank with water produces more displacement than the side does.更多还原
