| 摘 要： | 探讨了成都膨胀土的一些物理、化学性质,以吸力经验公式为基础,结合某路堤边坡工程,分析了膨胀土吸力对边坡稳定性的影响。采用“条分法”分别按照均质边坡、无孔隙水压力,均质土坡、有孔隙水压力,均质土坡、有孔隙水压力且坡顶开裂三种工况对膨胀土边坡稳定性进行预测分析,计算结果表明后两种情况下边坡的稳定性大大降低,并提出了防止边坡失稳相应的工程措施。

| Abstract: | The suction in the slope of expansive soil has a direct effect on the slope stability. This article discusses the physical and chemical characteristics of expansive soil in Chengdu. With one embankment slope as an example, this article utilizes polygon elements to forecast and analyze the result in the light of the suction experience formula of artificial neural network, with some improving engineering measures suggested. The result is very satisfactory. |
