甘南地区某高速公路滑坡治理浅析

Analysis on Treatment of A Highway Landslide in Gannan Area

当前国内外治理滑坡主要采用挡墙或抗滑桩并结合锚索防护的形式,不同类型的加固措施式效果不同,施工方法和工程造价亦不同。以甘肃省南部地区某高速公路发生的滑坡为例,通过软件分别进行了抗滑挡墙、圆形抗滑桩的稳定性验算,分别从工程可靠性、经济性对比了几种不同的处理方式并得出了一些结论。

At present,landslides at home and abroad are mainly treated by retaining walls or anti-slide piles in combination with anchor cable protection.Different types of reinforcement measures have different effects,and construction methods and project costs are also different.In this paper,a landslide occurred on a highway in the southern part of Gansu Province as an example.The stability of the anti-sliding retaining wall and the circular anti-sliding pile were verified by software.Several different treatments were compared from the reliability and economics of the project way and reached some conclusions.
