中文摘要：

采用有限元方法来分析单排大圆筒结构在波浪荷载作用下的倾覆，对不同埋深、不同径高比的大圆筒结构在波浪荷载作用下的转动进行了比较。计算结果表明，埋深的增大有利于该结构的抗倾覆稳定，而高度一直径比的增大则对该结构的抗倾覆稳定不利；高度．直径比较小时，埋深对结构转角发展的影响较小。

英文摘要：

The stability of quay walls consisting of large diameter cylinders, subjected to wave action, is investigated through two dimensional finite element analysis. The effects of embedment depth and height over diameter ratio on the performance of the cylinders is also evaluated. The results show that the stability of the quay walls will be increased with the embedment depth and decreased with the height over diameter ratio.
