摘   要 ：为根治某高速公路大型滑坡 ，根据地质勘察成果剖析其水文地质和工程地质情况 ，并通过现场踏 勘掌握滑坡的变形现状和变形发展阶段 ，从地质因素 、降雨因素和人类工程建设活动三个方面分析滑坡的变形 机制 ；基于滑坡的当前变形现状判断其稳定度 ，利用定量计算验证定性分析结果 ，并采用适当的应急抢险措施 防止滑坡变形规模进一步扩大 ， 同时也为永久治理争取有利的时间。结果表明： 准确地分析滑坡成灾机理是滑 坡治理的前提 ，并辅以定量分析进行验证 ，将定性分析与定量计算相结合的工作方法是制定针对性措施 、进行 大型滑坡治理的有效手段。

Abstract：In order to completely treat some large-scale landslide, investigation achievements were analyzed so that its hydrogeological and engineering-geologic conditions could be understood, furthermore in-site investigation was carried out to grasp landslide’s current deformation and development stage, three factors of geology, rainfall and human construction activities were combined to figure out deformation mechanisms; in addition, stability factor was determined based on current deformation condtions, and quantitative computation was applied to verify the accuracy of qualitative analysis, temporary treatments were adopted to control further deformation and save favorable time for perpetual treatment.The successful treatment case of some expressway large-scale landslide shows that correct mechanism analysis and stability computation is an effective approach in making pertinent measures and for large-scale landslide treatment.

Keywords：expressway; large-scale landslide; mechanism analysis; stability computation; landslide treatment
