摘要

爆炸排淤填石法广泛用于我国浅海滩涂防波堤的修建，但爆炸排淤填石堤坝的滑动稳定性，目前还没有有效的分析方法。首先通过对处于深厚淤泥中的填石坝体和坝侧土体的极限平衡分析，推导出计算此类堤坝稳定性安全系数的新方法。然后针对一个工程实例，将新方法与几种常用边坡稳定性分析方法的计算结果进行了对比，结果表明，新法优于其他几种方法，其结果较好地反映了堤坝的实际稳定性。

Abstract

The toe-shooting method has been widely used to build nearshore groynes in China. The proper method for analyzing the slope stability of this kind of groyne is however not found at present. Based on the limit equilibrium method a typical groyne located in a deep silt and soft soil mass aside is first analyzed. A new method calculating the factor of safety is then proposed for the slope stability of these groynes. Finally

the method presented and other four common methods are used to analyze the slope stability of a practical groyne. It is shown that the proposed method for slope stability of this groyne can give the more realistic factor of safety than the other four common methods.
