摘　　要：沙漠地区的风积沙路基在当地实际工程中应用较为广泛,传统的路基施工技术在沙漠地区并不完全适用,因此需要根据沙漠地区的实际情况进行技术创新和改进。依托具体的工程案例,对沙漠地区地质特征以及沙漠地区风积沙路基施工技术进行了研究。随着干密度的逐渐增大,内摩擦角呈现出相关的拟合线性变化,表现出逐渐增加的规律;干法振动试验相对于重型击实和湿法振动试验,风积沙的密实性能较为稳定。应力应变数值随着含水率的增加,表现出逐渐增大的变化趋势;同样应变情况下,干密度的大小与应力值呈现出正相关关系。The aeolian sand subgrade in desert area is widely used in project practice,and the traditional subgrade construction technology is not fully applicable in desert area,so technical innovation and improvement should be carried out according to the actual situation in desert area.In the paper,based on specific engineering cases,the geological characteristics of desert areas and the construction technology of eolian sand roadbed in desert areas are studied.With the gradual increase of dry density,the internal friction angle presents a relevant fitting linear curve,showing a gradual increase.Compared with heavy compaction and wet vibration test,the compaction performance of aeolian sand is more stable.With the increase of water content,the stress-strain values show a gradually increasing deformation trend.Under the same strain,there is a positive correlation between dry density and stress value.
