青海省某改建公路滑坡稳定性评价及处置措施

Slide stability evaluation and management measures of extension highway in Qinghai province

以青海省某改扩建公路滑坡为例,探讨滑坡的形成机制,通过计算分析对其稳定性进行了预测评价,并对不同治理措施进行了技术经济对比,提出了"锚索抗滑桩+锚索地梁+挡土墙+截排水沟+裂缝夯填"的复合工程治理方案,并论述了施工要点,以供参考。

Taking the slide of a certain extension highway in Qinghai province for an example, this article has been researching for its forming process, making forecasting and estimation of its stability according to the computational analysis. And with the technology and economy compari- son towards different management actions, a compound project management proposal of ＂anchor cable anti-slide pile, anchor cable patand, earth- retaining wall, cut-off drain, and crevice tamping＂ has been raised, and discusses the construction points for reference.
