| 摘 要： | 结合某山区高速公路路堑边坡工程实例,采用相当抗剪强度和相当剪应力之比值作为边坡稳定系数Ks,通过有限元方法对施工过程中的边坡变形和稳定系数变化规律进行研究.研究结果表明：根据边坡稳定系数Ks最小原则计算得到的最危险滑动面与现场勘探的边坡岩体内贯通结构面的位置基本吻合;不同施工阶段的边坡稳定系数Ks表明,需要对边坡的四级台阶均进行加固,才能保证该边坡的稳定.

| Abstract: | The ratio of relative strength and relative stress was taken as slope stable coefficient, slope deformation and the variational law of stable coefficient were studied combined with engineering practice of a mountainous expressway. The results show that the most dangerous plane calculated is accordance with the position obtained by measurement. In order to ensure the stability of slope,it is necessary to solidify four-step sidestep of slope according to stable coefficient in different construction phases. |
