基于落球式测试法的宕渣路基施工质量检测技术研究

Research on Construction Quality Inspection Technology of Slag Subgrade Based on Falling Ball Test Method

随着道路网络建设的不断完善,公路里程持续向山区延伸。山区公路挖掘隧道产生的大量粗骨料可用于路堤的填筑,特别是在高速公路,隧道开采而产生的矿渣和大量的土石方是其主要的填筑材料。但在此领域,相关研究尚不完善。为此,对矿渣的压实特性、力学特性及充填试验技术进行了探讨,为宕渣路基施工提供理论依据。

With the continuous improvement of the road network construction,the highway mileage continues to extend to the mountain area,and a large amount of coarse aggregate produced by excavation of tunnels is used for embankmentfilling.Especially on the basis of expressway,slag and a large amount of earthwork produced by tunnel mining are the mainfilling materials.But in thisfield,the related research is not perfect.Therefore,the compaction characteristics,mechanical properties andfilling test technology of slag are discussed.
