支撑渗沟在膨胀土浅层路堑边坡处治中的应用

Application of Supporting Blind Drains in the Shallow Cutting Slope Treatment of Expansive Soil

边坡对道路工程的安全起着至关重要的影响,通过结合工程实例,在分析郴州某道路膨胀土浅层路堑边坡发生破坏原因的基础上,结合支撑渗沟的作用原理以及尚未完全破坏的坡面人字形骨架,提出了“支撑渗沟+尚未破坏的人字形骨架+坡脚恢复挡土墙”的处治方案,相比其他的处治方案更经济、易施工,且防护和排水效果明显。可作为其他类型工程的借鉴方案。

The slope plays a crucial role in the safety of road engineering.Through engineering examples,based on the analysis of the reasons of the damage of the shallow cutting slope of expansive soil on a road in Chenzhou,and combined with the action principle of supporting blind drains and the herringbone skeleton of the slope surface that has not yet been completely damaged,this article proposes a treatment plan of"supporting blind drains+undam-aged herringbone skeletons+retaining walls at the foot of the slope".Compared with other treatment plans,it is more economical and easier to construct with obvious protection and drainage effects,and it can serve as a reference plan for other types of projects.
