| Abstract: | Based on a case of Heifangtai landslide region in Yongjing,Gansu,the relations between landslides and related geo-environmental factors were analyzed.Our conclusion is that the most unfavorable working conditions of landslide are：the height of landslide is H125 m,the slope of landslide is 30°i≤35°,the thickness of loess is 35h≤40 m,the thickness of the sliding body is d30 m.Proposals are also given here. |
