摘要
分析地下水渗流对岩土边坡稳定性的影响,推导了透水边坡在地下水渗流条件下边坡稳定系数的解析表达式,采用非线性规划中的变尺度方法,求出最危险圆弧滑动面的位置。在高孔隙水压力条件下,采用简单条分法(W.Fellenius)和变尺度法首先确定最危险圆弧滑面的位置,然后,再利用严格解的Spencer方法或Morgenstern-Price方法,求最危险滑面的稳定系数。计算了某工程路堑边坡稳定系数和渗流对边坡稳定性的影响系数。
The influence of groundwater seepage on stability of soil and rock slope is analyzed. The analytic solution of stability of water-penetration soil and rock slope is set up under ground water seepage. The most dangerous circle slip surface is located with DFP change-scale method of nonlinear programming. In the condition of high pore-hydraulic pressure, the most dangerous circle slip surface is located with Fellenius Method and DFP change-scale method. Then the safety factor of the most dangerous circle slip surface is evaluated with Spencer method or Morgenstern-Price method. The influence coefficient of seepage on slope stability is calculated in a cutting slope.
