| 摘 要： | 降雨会改变地基表层土的含水率,影响土的强度,诱发山体滑坡。本文基于室内直剪实验,测定了某高速公路边坡膨胀土在不同含水率下的物理力学参数,并通过有限元软件计算不同参数下此边坡的稳定系数,得出的计算结果与工程实际情况相一致,初步探讨降雨对膨胀土边坡稳定系数的影响。

| Abstract: | The rainfall will change the moisture content of surface soil foundation,influence soil strength and cause landslides.Based on Direct Shear experiment this article measured a highway of slope expansive soil to gain physical and mechanical parameters under different moisture content and calculated stability factor in this slope under different parameters by the finite element software.The results obtained are consistent with the practical engineering,preliminary study the rainfall to the influence of the exp... |
