摘要
本文介绍了在既有线上以优质道碴更换石灰石道碴的工艺，根据轨道基本参数的现场测试结果，分析混合道碴道床的稳定性，探索改善道床工作状态的适用方案。
The paper introduces the technology for replacing the limestone ballast by the superior quality ballast on the existing railway lines. Based on the testing results in situ for the basic parameters of the railway track, the stability of the track bed with mixed ballast is analyzed, and the applicable scheme for improving the working state of the track bed is explored.
