摘要
新疆古尔班通古特沙漠风积砂分选良好,矿物成分以石英为主,砂粒磨圆度好,具有孔隙率大、内摩擦角小、承载力低等特性.通过在沙漠北部、中部和南部试验段进行的专题工程地质研究,介绍了新疆准噶尔盆地古尔班通古特沙漠风积砂的基本物理力学特性和压实性、压缩性、渗透性、冻胀性等工程地质特性.
The Aeolian sand in Guerbantonggute desert is mainly composed of quartz. The sand grains are well-sorted and of high psephicity. The engineering geological properties can be characterized by high porosity, low friction angle and 10w bearing capacity. Some thematic engineering geological researches have been conducted in the north, middle and south section of the desert, through which the basic physical mechanics properties of the sand, such as compactibility, compressibility, permeability, frost and heave, have been generalized in this paper.
