摘要: 为探究巨型冰楔滑坡起动理论,以阿塔巴德滑坡为研究对象,分析巨型冰楔滑坡的形成条件与诱发机制。实地考察阿塔巴德村所在区域的地形地貌、气候、工程地质、水文地质及地震与新构造运动等环境条件;通过理论分析得出阿塔巴德滑坡诱发机制。结果表明:阿塔巴德滑坡的形成原因为高寒高海拔地区特殊的地形地貌条件、气候条件、工程地质条件、水文地质条件及地震与新构造运动;2010年1月4日发生的阿塔巴德滑坡是通过地下水裂纹与冰楔冻胀反复作用诱发而形成,此后发生的多次次生滑坡则由冻结与融化交替形式的冻融作用发育。

Abstract: In order to study strarting theory of huge ice-wedge landslide, its formation conditions and triggering mechanism were analyzed with Atabad landslide as research object. Field investigation was conducted on classic geomorphy, climate, engineering geology, hydrogeology, seism and neotectonic movement in Atabad village, and triggering mechanism was obtained through theoretical analyses. The results show that landslides in Atabad are caused by special geological factors of alpine high altitude area, including geomorphy, climate, engineering geology, hydrogeology, seism and neotectonic movement. The landslide on January 4, 2010 was induced by groundwater crack action and repeated frost heaving of ice wedge, while several secondary landslides which occurred after that were mainly developed by freeze-thaw actions.

Key words: Atabad landslide, formation conditions, triggering mechanism, Karakoram highway, groundwater crack effect, freeze-thaw actions
