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水渠道地基的稳定性。据初步研究 ,沙漠区风洪积壤土类土 ( Q4 eol-pl4 )、风积极细砂 ( Q3 eol4 )具有湿陷性 ,其湿陷性与砂土的成因、分布。
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.
