中文摘要：

随着高等级公路不断向山岭重丘区延伸，滑坡灾害已严重威胁到山区已建和在建高速公路的运营与建设安全，并给国民经济和生命财产造成巨大损失。针对国家高速公路十堰一天水联络线（G7011）陕西境鄂陕界至安康公路第A—CD48标段大型牵引式滑坡进行研究，通过对滑坡形成的地质环境、滑坡机制和类型以及滑坡的稳定性评价分析，提出针对该滑坡的综合治理方法和措施，即采用锚索抗滑桩稳定边坡，同时做好地面的排水系统以及坡面的生物防护，最后对滑坡在治理过程中的关键技术问题进行讨论。

英文摘要：

The landslide directly affects the operation and construction security of highway which has built in mountain, at the same time, the landslide also causes a great loss to the national economy and the life safety. Based on the national highway Shiyan to Tianshui link（ G7011 ）, this paper analyzes the large scale tractive landslide of expressway which is in the borders of Hubei and Shaanxl provinces to Ankang, through the geological environment of landslide formed, landslide mechanism and type, stability evaluation, the control methods and measures are put forward： anti-slide piles with double rows, ground drainage system and biological protection. Finally, the key technical problems in the landslide treatment are discussed.
