摘要
文章以某公路泥质粉砂岩滑坡处治工程为例,结合区域地质资料与工程地质勘探,分析滑坡特征及原因.采用Geo-slope软件Morgenstern-Price法,在反算岩体参数的同时,计算边坡剩余下滑力.根据边坡下滑力采取直径为 2 m的圆形抗滑桩进行边坡主体加固,并设置长泄水孔进行坡体排水,保障了边坡的安全稳定,可供类似边坡防护处治参考.
Abstract
Taking a highway argillaceous siltstone landslide treatment project as an example,combined with regional geological data and engineering geological exploration,this paper analyzes the characteristics and causes of landslide.Geo-slope software Morgenstern-Price method is used to calculate the residual sliding force of the slope while the rock mass parameters are inversely calculated.According to the sliding force of the slope,a circular anti-slide pile with a diameter of 2 m is adopted to reinforce the main body of the slope,and the long weep hole is set up for slope drainage,so as to ensure the safety and stability of the slope,which can be used as a reference for similar slope protection treatment.
