摘   要 ：為根治某高速公路大型滑坡 ，根據地質勘察成果剖析其水文地質和工程地質情況 ，并通過現場踏 勘掌握滑坡的變形現狀和變形發展階段 ，從地質因素 、降雨因素和人類工程建設活動三個方面分析滑坡的變形 機制 ；基于滑坡的當前變形現狀判斷其穩定度 ，利用定量計算驗證定性分析結果 ，并采用適當的應急搶險措施 防止滑坡變形規模進一步擴大 ， 同時也為永久治理爭取有利的時間。結果表明： 準確地分析滑坡成災機理是滑 坡治理的前提 ，并輔以定量分析進行驗證 ，將定性分析與定量計算相結合的工作方法是制定針對性措施 、進行 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
