随着我国高速铁路建设的迅猛发展,用作路基填筑的材料越来越多,圆砾土就是一种较为理想的材料.虽然圆砾土作为路基填料具有强度高、稳定性好等诸多优点,但我国现有铁路路基填方压实标准对粗粒土的压实质量控制仅有定性指标,其施工工艺和检测方法在路基施工技术规范中却没有相应的具体要求.使路基填筑施工难于有效控制压实质量.本文结合青荣城际铁路圆砾土路基的试验和施工情况,对圆砾土填筑路基的施工工艺和质量检测控制进行了初步探讨.

With the rapid development of China's high-spee-d railway construction, the material used for roadbed constr-uction, more and more, gravel soil is a kind of ideal material. Although the gravel soil as roadbed fil er has the advantages of high strength, good stability and many other advantages, but the present railway roadbed fil ing compaction standard of coarse grained soil compaction quality control only quail-tative indicators, the construction technology and detection method in the technical specification in subgrade constru-ction, but no specific requirements for the corresponding.The subgrade fil ing construction is difficult to effectively control the quality of compaction . this paper discussed the round gravel soil Roadbed construction technology and quality control testing.
