以京化高速公路二期KC-3标段岩质高边坡为研究对象,应用有限元分析软件ANSYS建立三维数值模型,模拟边坡在重力作用下的变形情况,借助于有限元强度折减法对边坡材料进行强度折减,直至边坡的塑性区实现贯通,得到边坡临近破坏时的变形情况,此时的折减系数即为边坡的安全系数。结果表明,边坡的安全系数为1.04,远小于安全控制标准,极易发生边坡失稳。

Taking the high rock slope in the second- term KC-3 engineering of Jing-Hua highway as the research object, the three-dimensional numerical model is established by the finite element analysis software ANSYS. The deformation is simulated when the slope is under the action of gravity. By means of finite element strength reduction to reduce the slope material strength until the slope of the plastic zone reaches run through, the deformation of the slope near failure is obtained, at this point the reduction factor is the slope safety factor. The results show that the high slope safety factor is 1. 04, far less than the security control stand- ards, and which is prone to slope instability.
