某高速公路滑坡特征及治理措施研究

The Analysis on the Landslide Mechanism in the freeway

以河南某高速公路高填方路段滑坡工程为背景,现场勘探了滑坡变形特性,分析了滑坡发生的诱发因素,即地形和地层特征以及持续降雨,在基于强度折减的有限元分析基础上,提出了采用抗滑桩并辅以锚杆和预应力锚索的处理方案,现场实施效果良好,可为类似工程的设计提供借鉴。

Based on an landslide engineering in high embankment of freeway in Henan Province,the deformation characteristics of the landslide was surveyed. The factors that affected the landslide, the characteristics of topography and soil, continuous rainfall, were analyzed. The 2D finite element method with reducedshear strength was used to analyze the management scheme, as anti-slide pile and rockbolt and prestressed anchor lock. The feasibility was verified by the field practice.
