摘要： 湖北省某高速公路高边坡，在路堑区发生了变形破坏，为了工程安全及减小社会影响，对该段病害边坡亟需进行治理。首先收集边坡变形资料，进行地质勘察，查明该滑坡体工程地质和水文条件，进而对其成因机理、变形特征及稳定性进行了分析，并进行坡体综合处治设计。结果表明，目前该病害高边坡变形仍处在发展阶段，在暴雨或连续降雨情况下处于不稳定状态，在地震状态下处于欠稳定，需采取钢管桩（抗滑桩）护坡+钢轨桩挡土墙锁脚+封闭裂缝+排水措施的综合治理方案进行加固。

Abstract: The high slope of a highway in Hubei Province was deformed and damaged at the cut area. For construction safety and minimizing the community impact, highway slope hazards within this section are in an urgent need of mitigation. The slope deformation data were collected, the geological and hydrological conditions ate the potential sliding body were investigated and the stability was evaluated. The landslide mitigation measures were also designed and implemented. The results show that high slope deformation hazards are still in the development stage. The slope is in an unstable state under the heavy precipitation, continuous rainfall and under the seismic conditions. As comprehensive mitigation measures, the steel pipe pile as antisliding pile, railway track steel segment as the retaining wall toe protection, seal off cracks at surface and promoting drainage were applied.

Key words: high slope, contribution factors, deformation characteristics, stability, mitigation measures
