干旱荒漠区填筑风积沙路基稳定性研究

Research on the Stability of Aeolian Sand Subgrade in Arid Desert Area

风积沙是干旱荒漠区公路建设中常用的筑路材料,但在盐渍土地区高等级公路中进行风积沙填筑、砂砾土包边的施工工艺及可行性尚待深入研究。为此,文章依托新疆G0612若羌至民丰沙漠高速公路工程项目,结合室内及现场试验,研究了不同路基厚度及砂砾土包边宽度对风积沙路基稳定性的影响。研究可为推动风积沙路基修筑技术应用及工程质量提升提供案例参考。

Aeolian sand is a commonly-used road material in highway construction in the arid desert area,but the construction technology and feasibility of aeolian sand filling and gravel soil edging in high-grade highways in the saline soil area need to be further studied.Therefore,based on the project of Xinjiang G0612 Ruoqiang-Minfeng desert expressway,combined with laboratory and field tests,the effects of different subgrade thickness and gravel soil edging width on the stability of aeolian sand subgrade are studied.The research can provide the case reference for promoting the application of aeolian sand subgrade construction technology and the improvement of engineering quality.
