摘　　要：高速铁路路基水泥级配碎石填筑质量直接影响高速铁路运营的平顺性和安全性。文章系统总结了高速铁路路基水泥级配碎石填筑质量控制要点,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,以期对路基填筑质量控制和评价具有指导意义。The quality of cement graded crashed stone filling in high-speed railway roadbed directly affects the smoothness and safety of high-speed railway operation. This paper systematically summarizes the key points of quality control of cement graded crashed stone filling in high-speed railway subgrade, and puts forward the qualitative evaluation criterion that the compaction quality of cement graded crashed stone should be “intrinsically and well-compacted”, with a view to guiding the quality control and evaluation of subgrade fi lling.
