基于精密测量技术的高速铁路运营安全监测研究

摘要

In the operation stage of high speed railway , it is mainly based on the CPⅢcontrol network to monitor the track smoothness and ensure the safety of train operation .The stability and accuracy of CPⅢ control points affect the operation safety monitoring re-sults.In this paper , we propose a method to detect the stability of the CPⅢcontrol points based on the precision measurement tech-nology, in order to find out the control points of the large point errors , and ensure the reliability of the CPⅢcontrol points.%高速铁路运营阶段，可借助CPⅢ控制网对其轨道平顺性进行监测，以保障列车运行安全。 CPⅢ控制点的稳定性和位置精度决定运营安全监测的可靠性。本文提出了基于精密测量技术的CPⅢ控制点稳定性检测方法，以发现存在较大点位误差的控制点，确保参与监测的CPⅢ控制点精度。
