摘要
某高速公路施工过程中,K3+965—K4+195段深挖路堑所处自然坡体呈现欠稳定状态,边坡开挖基本成型后,出现局部滑塌,裂缝发育等不良现象,坡体有整体滑移的趋势。以该工程实例为背景,较为详细地分析了边坡的失稳原因,并且结合各方因素对边坡的治理方案进行了比选论证,最终确定了该路段的加固处治方案。
For a project example as a background, this paper illustrated the cause of slope instability in detail. And combined with all the factors, it also had the comparison demonstration on the slope treatment scheme, ultimately determined the reinforcement treatment scheme of the road.
