摘要
三峡机场灯光带滑坡，属典型的人工加载“后推式”碎石土滑坡类型。该滑坡治理前，稳定系数仅１．０７，处于极限平衡状态，不仅严重阻碍机场灯光带导航系统的建设，且危及相距仅２００ｍ的汉宜高等级公路。该滑坡通过工程治理，达到了预期目的，收到了良好的社会和经济效益。
The landslide, situated in the lighting zone of the Three - Gorges Airport of Yichang City, is a typical rear - pushing landslide composed of pebble and soil with load - adding activities of human being. Its stability factor was only 1. 07 which suggests threshold stable state before any measures was carried out there. This landslide was threathening construction and normal operation of the lighting system and the Wuhan - Yichang Highway which is just 200m away. The engineering efforts tackling the landslide have reached the goals and acquired rather good social as well as economic benefits.
