| 摘 要： | 山区公路经常沿水库修筑,水库的蓄水与放水能引起水位的循环升降变化.水位变化对边坡稳定有较大影响.基于Plaxis有限元软件的渗流计算和边坡稳定的强度折减法计算功能,以一个实际库岸边坡为算例,分析了水位升降变化及下降速率、土体渗透系数、是否考虑超孔隙水压力对边坡稳定性的影响.分析结果表明,当土体设置为排水条件时,不管水位...

| Abstract: | The road in mountain area is always built beside reservoir.The water level will change when storing water or discharging water,which will influence the slope stability.Based on a certain bank slope project,the influence of water level fluctuation,decrease velocity,soil permeability,and excess pore water pressure on stability of slope was analyzed through seepage field calculating and strength reduction calculating with soft ware Plaxis.It is shown that(1) when the soil condition is set to be drained,the sta... |
