| 摘 要： | 本文中采用时域显式有限元方法,将库底淤积砂层模拟为重流体,以小湾拱坝为例,分析可压缩库水条件下库底饱和淤积砂层对高拱坝地震反应的影响。计算结果表明,从总体上来说饱和淤砂层的存在对高拱坝地震反应影响较小,但是仍有一些局部反应的变化值得注意。

| Abstract: | Taking the Xiaowan arch dam as an example,the effects of saturated sediment on the seismic response of high arch dams are analyzed by using the time-domain explicit finite element model and modeling sediment media as the heavy fluid.The computation results show that,as a whole,the effects of the saturated sediment layer are ignorable.However,the presence of the sediment layer maybe causes some local changes which are worthy to be noticed. |
