| 摘 要： | 根据Boussinnesq应力公式和Mohr-Coulomb破坏准则,导出天然软土地基上路堤临界高度的计算式。考虑地表硬壳层对路堤荷载的扩散作用,分析硬壳层厚度和刚度对路堤临界高度的影响。导出的路堤临界高度计算式在特殊条件下可简化为巴布科夫公式和Fenenius公式。

| Abstract: | According to Boussinnesq stress formula and Mohr-Coulomb failure criterion,the calculation formula of embankment critical height on natural soft foundation is educed.Considering the diffusion of embankment load by surface hard shell,the influence of hard shell thickness and rigidity on embankment critical height is analyzed.The formula of embankment critical height in this paper can be simplified into Babu-Cove Formula and Fenenius Formula under special situations. |
