1980～1981年我公司用喷锚网加固三段线路边坡共6118米~2,取得良好效果。其中:1号铁路线8+50～9十50边坡高20～42米,边坡度1:0.5。边坡上层30米均为强风化的透辉石、透闪石,裂隙和碎片间充满粘土。下层12米稍风化,岩层整体性较好。由于雨水冲刷,上层裂隙和碎块间的粘土被雨水带走,造成边坡失稳垮塌。由于边坡顶有一条混凝土公路,边坡不可能改缓。经方案比较,大胆采用了用喷锚网加固边坡,即12米
From 1980 to 1981, our company reinforced 6118m ~ 2 of the three sections of slope by spraying anchor net, which achieved good results. Among them: No. 1 railway line 8 +50 ~ 9 10 50 slope height of 20 to 42 meters, the slope of 1: 0.5. The top 30 meters of the slope are strongly weathered diopside, tremolite, cracks and fragments filled with clay. The lower 12 meters slightly weathered, rock integrity is better. As the rain washed, the upper cracks and debris between the clay was taken away by the rain, causing the collapse of slope instability. Since there is a concrete road at the top of the slope, the slope can not be slowed down. The program comparison, the bold use of spray anchor network reinforcement slope, that is, 12 meters
