湿陷性黄土路基试验段施工技术探讨

针对湿陷性黄土路基施工不当,易发生路基沉陷、路基陷穴、边坡破坏等病害的缺陷,通过试验段路基填筑工艺试验,分析研究了采用湿陷性黄土填料分层填筑路基过程中,松铺厚度、碾压遍数与路基压实度之间的关系,据此制定了最佳施工方案,以达到提高路基质量,减少后期路基病害发生的目的。

On exploration for construction technique at collapsible loess roadbed trial section

According to some defects on the collapsible loess road,including improper construction,frequent roadbed settlement,sunken holes of roadbed,and damages on slopes,the paper analyzes and researches the relationship among the loosing paving thickness,compaction times and roadbed compaction by adopting the collapsible loess filler layered filling according to the roadbed filling craft tests at the trial section,and makes the optimal construction scheme,so as to improve the roadbed quality and reduce the roadbed diseases in later periods.
