| 摘 要： | 利用三维非线性动力有限元方法及笔者编制的三维动力程序，对深覆盖层上沥青混凝土心墙堆石坝的动力特性进行了详细分析，笔者将Ｒ．Ｗ．克拉夫提出的关于混凝土坝的处理方法移植到堆石坝动力分析中，从而可利用地面波求解覆盖层上堆石坝的动力结构问题。通过实例计算和分析，表明覆盖层的分布对其上堆石坝的地震响应影响较大。

| Abstract: | ith the application of a FEM program for 3-D nonlinear seismic response calculation,the dynamic characteristics of asphalt concrete core rockfill dams on deep overburden are studied in very detail in this paper.In the study, the author transplants the method presented by Clough R.W for concrete dams to rockfill dams,thus dynamic structure problem of rockfill dams on deep overburden can be solved with ground wave importation. Through calculation and synthetical analysis,the paper draws conclusions about earthquake response of rockfill dams on deep overburden. |
