| 摘 要： | 应用非稳定渗流计算原理,求解不同渗透系数和降水速度时水位下降过程中边坡内部的浸润线.通过求出的浸润线,计算了边坡在浸润线影响下的的稳定性.通过对比不同渗透系数和下降速度下边坡的安全系数,分析并解释这些因对边坡稳定影响原因.计算结果显示在水住变化过程中,边坡的安全系敖呈现出先变小再变大的变化规律,即边坡存在最危险的水位时...

| Abstract: | the principle of non-steady flow is used to solve different permeability coefficients and the speed of the saturation line inside slope during the water level going down.Obtained by the saturation line,calculated the slope stability under the saturation line.By comparing the rate of decline of different permeability and the safety factor of slope,it analyze and explain these reasons effecting the slope stability.The results show the safety factor of slope appears the law of changing from smaller to bigger d... |
