摘要

为提高养路机械作业精度，保证列车运行稳定性与安全性，采用基于固定点的养路机械作业施工方法。对EM-SAT 测量系统的原理及方法进行了分析，并对其测量作业效果进行了试验验证。结果表明：EM-SAT 的这种基于固定点的轨道长弦测量方式在国内的既有线及新建线均得到很好的应用。

Abstract

For improving rail maintenance machine operation precision and ensuring the stability and safety of train operation,maintenance machine operation based on fixed points was adopted. The measurement principle and method of EM-SAT measurementsystem were analyzed, and the results were verified by experiments. The results showed that EM-SAT, the track long string measurementmethod based on fixed points, could be well applied in the domestic existing and new lines.
