| 摘 要： | 腾格里沙漠南缘风积砂土地基的湿陷性，直接影响建设中的引入渠道地基的稳定性。据初步研究，沙漠区风洪积壤土类土（Ｑ４＾４ｅｏｌ－ｐｌ）、风积极细砂（Ｑ４＾３ｅｏｌ）具有湿陷性，其湿陷性与砂土的成因、分布、颗粒组成及干密度有明显的关系。

| Abstract: | In this article a study is made on the collapsibility of eolian sand in a desert area for the purpose of assessing the foundation stability of the irrigation canals on the south edge of Tenggeli Desert. The study shows that the eolian untra\|fine sand ( Q 3eol 4)and the eolian\|diluvial loam ( Q 4eol-pl 4) possess collapsibility. The collapsibility of the sand and the loam shows a clear correlation with their origin, distribution, particle composition, and dry density. |
