| 摘 要： | 黄土窑洞在我国北方分布极广,目前仍有四千万人居住在各种形式的黄土窑洞中。长期以来连阴雨是造成窑洞坍塌的主要原因。本文根据近代土壤水能量原理,结合室内外的实验研究,证明在黄土窑洞洞顶土层设置砂层,可以防止和减少土壤水分的下渗。

| Abstract: | In north China,there are about 40 million people living in many kinds of loess caves.The collapse of caves were caused mainly by a contineous rain for a long period in autumn.Based on the energy theory of soil water,it was shown by experiments both in laboratory and in the field that a sand layer within the loess on the top of the caves can effectively decrease rain percolation.The method,therefore,is useful in preventing the eaves from collapse. |
