【摘要】：对重庆地区最常见的泥岩采用边坡稳定性分析中的图表法,简明地分析确定了泥岩的极限坡率。得出了微风化泥岩,坡高在50m以内,其极限放坡系数可以为1∶0——极限坡率=∞,也就是不放坡,垂直开挖的结论。应用此结论,解决了垫江县迎春河涵洞的开挖过程中,受场地限制无法达到设计放坡系数的实际问题,节省了工程造价、缩短了施工工期;还解决了垫江县桂西大道修建过程中两边征地不足,无法满足设计放坡系数的问题,节省了工程造价、减少了土地占用。
[Abstract]:In this paper, the most common mudstone in Chongqing area is analyzed and the limit slope ratio of mudstone is determined by using the chart method of slope stability analysis. The conclusion that the slope height is less than 50m and the limit slope coefficient can be 1: 0- limit slope ratio = 鈭，
