摘　　要：以爆炸排淤填石法筑堤为背景,分别用传统方法和数值分析法对这种处于深厚淤泥中、断面形状复杂的爆炸排淤填石堤坝进行了最终沉降量的计算。计算结果表明,传统的沉降计算方法因为无法处理断面形状复杂、大埋深和深厚淤泥地层等问题,计算效果都很不理想;相反,利用PLAXIS有限元软件能在一定程度上解决这一问题,计算结果与工程实测值也比较接近,优于传统的沉降计算方法。In this paper,the settlements of embankment constructed by toe-shooting method were analyzed by various traditional settlemrnt calculation methods and finite element method, which lies in deep silt layer and has a complex cross-section.Calculation results showed that the traditional settlement calculation methods did not work well, because they were not adequate for such an embankment with complex cross-section and deep depth in thick silt layer. Further more,it showed that PLAXIS were better than traditional settlement calculation methods and can meet the measured settlement data from a real embankment.
