| 摘 要： | 本文在东南沿海的海堤结构型式及有关潮位、波浪和海淤土强度的资料基础上，进行了非稳定渗流有限元法计算，以及在潮位和波浪作用下的抗滑整体稳定性计算分析。比较了单圆弧滑动和复合圆弧滑动以及加筋抗滑的有限元法计算结果，认为海淤软基抗滑计算以复合圆弧更为合理，斜坡式比直立式海堤的抗滑稳定性稍好，结合三防(防浪、防冲、防渗)考虑，当以带平台的复式断面海堤结构型式为好，但仍应因地制宜。

| Abstract: | The non-steady seepage flow analysis and sliding stability analysis for existing dykes in southeast coast of China are carried out. The comparisons of computational results of FEM analysis for different types of sliding show that it is more reasonable to use the composite circular arc sliding mode for sliding analysis. The results also show that the stability of dykes in sloping shape is better than that of vertical shape. |
