摘　　要：依托高速铁路建设工程质量监督检查的长期实践,系统分析了路基工程水泥级配碎石填筑质量的控制程序,提出水泥级配碎石压实质量应“内在密实、板结良好”的定性评价标准并纳入现行验标中执行;通过对水泥级配碎石填筑实体的钻芯取样,探索芯样抗压强度和完整性与水泥级配碎石填筑质量之间的关系,提出评价水泥级配碎石填筑质量新指标。Based on the long-term practice of quality supervision and inspection of high-speed railway construction project,the quality control procedure of cement graded gravel filling in roadbed project is systematically analyzed,and the qualitative evaluation standard of cement graded gravel compaction quality should be"intrinsically dense and good compaction"is put forward and implemented into the current inspection standard.The relationship between the compressive strength and integrity of the core sample and the quality of cement graded gravel filling is explored through drilling core sampling of cement graded gravel filling entity,and a new index of cement graded gravel filling quality is proposed.
