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. © 2020 China Safety Science Journal
