巨粒土填筑技术在高速公路路基施工中的应用

Application of Giant Soil Filling Technology in Expressway Roadbed Construction

依托实际工程,详细阐述了巨粒土填料路基施工技术要点,即基底处理、施工准备、摊铺、整平、碾压等,施工完毕后分别对巨粒土填料路基平整度、压实度、经济性进行评价分析。研究结果表明,巨粒土填料路基碾压完毕后平整度和压实度良好,巨粒土填料中大粒径颗粒可形成骨稳定骨架结构,小粒径颗粒将骨架内部孔隙填充,最终构成完整的路基结构。

Based on the actual project,this paper elaborates the key points of the construction technology of the giant soil fill roadbed,namely,base treatment,construction preparation,paving,leveling,rolling,etc.After the construction is completed,the smoothness,compaction and economy of the giant soil fill roadbed are evaluated and analyzed respectively.The research results show that the smoothness and compaction of the giant soil fill roadbed are good after the rolling is completed.Large particle size particles can form bone stable skeleton structure,small particle size particles fill the internal pores of skeleton,and finally form a complete subgrade structure.
