摘要： 公路滑坡治理不仅能保证交通畅通、减少经济和财产损失，而且能改善已遭到破坏的生态环境。目前我国治理公路高陡边坡、滑坡的主要措施有SNS柔性防护技术、喷锚网支护技术、抗滑桩体系。而抗滑桩则由于具有适应性强、工期较短、抗滑能力强等优点成为滑坡治理工程中主要方法之一。通过对某公路滑坡的稳定性进行详细分析，并结合该滑坡工程地质特征及危害范围等因素，对滑坡治理方案的比选，采取了以抗滑桩为主，结合锚杆和挡土墙为辅的综合治理方案，达到了预期目标，为同地区相似滑坡治理工程提供了经验。

Abstract: Effectively mitigating the highway landslide can not only to ensure the smooth flow of traffic and reduce the potential economic and property losses, it can also improve the compromised ecological environment. The popular highway slope mitigation methods are Soft Net System (SNS), ground anchor with netting and shotcrete system and sliding resisting caissons. The sliding resisting caisson method has the advantage of applicable in landslide with different conditions, short construction schedule and fairly good results and has been used as a major landslide mitigation tool. This paper presents a case history of the evaluation of a highway landslide. Different mitigation methods are compared based on the sitespecific conditions and the sliding resisting caisson method that combined with ground anchors and retaining walls were selected. The results are satisfactory.
