| 摘 要： | 文章运用对称边坡三维安全系数显示解,确定三维对称边坡的临界滑动面.假设对称边坡的滑动面是椭球面,改变滑面入口点位置和椭球的中心点位置,应用对称边坡三维安全系数显示解,计算得到对应最小安全系数的滑动面,即为三维临界滑动面.算例表明:初始正应力的假设对最终安全系数的结果影响不大,从而保证该方法的合理性与有效性；当边坡宽高比...

| Abstract: | Based on the explicit solution to the three-dimensional safety factor of a symmetrical slope,the critical slip surface of the three-dimensional symmetrical slope is yielded.Assuming that the shape of the slip surface of the symmetrical slope is ellipsoidal,and by changing the positions of the entry point of sliding surface and the center point of the ellipsoid and applying the explicit solution to the three-dimensional safety factor of the symmetrical slope,the slip surface corresponding minimum safety fact... |
