摘要 以甘肃永靖县黑方台滑坡群为例,通过分析影响滑坡地质灾害的滑坡高度、滑坡坡度、黄土厚度、滑坡厚度等地质环境因子的敏感性分析,确定了研究区最不利的滑坡工作状况为:坡高H>125m、坡度30°<i≤35°、黄土厚度35<h≤40m、滑体厚度d>30m.并就进一步的研究提出了建议. 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.
