摘要
用水体位移有限元分析库水底部含有淤沙对刚性坝动水压力的影响 .将淤沙作为弹性材料 ,对材料参数和不同厚度淤沙对动水压力的影响进行了详细的讨论 .
A displacement type fluid element technique is developed for two dimensional dynamic analysis of a system composed of a rigid dam,water in the reservoir,and sediment on the reservoir bottom.Sediment is an elastic material in the model.The results of dynamic pressure varying with sediment thickness and material parameter are reported.
