| 摘 要： | 荷载分布为梯形、软土地基因固结强度会提高是路堤下软土地基承载力的主要特征。基于这种特点, 推导了能考虑软土固结影响的地基承载力计算公式, 研究了其计算方法, 并用软土地基上路基填筑实例进行了对比分析, 计算结果与工程试验结果吻合良好, 为计算路堤下软土地基承载力及其增长、推算各阶段路堤填筑安全高度提供了一种有效方法。

| Abstract: | The trapezoidal load and increase of bearing capacity under the influence of consolidation are the main features of a soft foundation under embankment. On the basis of these features, this paper presents a method for assessing the bearing capacity of a soft soil foundation under embankment. In addition, the method has been applied on two embankment test data to check its applicability. |
