摘要
在假定软土及上覆硬壳的不排水抗剪强度随深度的变化分属两种线性形式时，可导出双层地基上路堤的稳定性分析式，进而对切层面滑动条件、滑弧下切深度及双层地基承载力进行了分析与讨论，并以破坏堤实测数据为参照，与其他分析方法作了比较。
Assuming that the variation of undrained shear strength of soft soils and of the overlying crust increase and decrease linearly with depth, the stability analysis formula of embankment on double-layer subbgrade have been derived. By the formula, the analysis and discussion of the slip conditions to slip along the overlying crust plane or the rigid undelayer plane, the depth of the slip circle and the bearing value of doublelayer subgrade have been obtained. In addition, measared data of actual failure embankments have been compared with the results obtained by stability analysis formula.
