摘　　要：根据陕北黄土丘陵区窑洞大量的实地调查,对窑洞坍塌原因进行了分析,结果表明,陕北黄土丘陵区窑洞后壁土崖的不稳定是坍塌的主要原因,据此提出了建窑时的技术措施,需要对土崖的高度和坡度有一定的限制,规定将土崖高度限制在12 m以内是比较安全的.The collapsing reasons of cave dwelling of loess hills in Northern of Shaanxi are researched. On the basis of field investigation of cave dwelling of loess hills, it is found that the unstability of the back wall of cave dwelling is the most important reason of collapsing, put forward that the altitude and slope of soil precipice should be limited to some extent, and 12 meter high of cave dwelling is suitable and safe, and also puts forward some constructive suggestions such as stable forms and soil precipices of cave dwelling of loess hills in Northern of Shaanxi.
