胶济客专既有铁路轨道控制网精密测量方法研究

On the Precision Measurement Method of Track Control Network Transformation of the Existing Jiao-Ji Passenger Dedicated Line

轨道控制网是既有线轨道运营维护的控制基准,它为列车运营时平顺性和舒适性提供了可靠的保证。该文依据胶济客专运营维护阶段的实际情况,在介绍线路平面控制网和高程控制网构建的基础上,提出一种适合既有线轨道控制网(CPⅢ)改造精密测量方法和技术措施,并对测量成果进行分析评价。该成果对后续的既有运营线路轨道维护提供了技术保障。

Track control network is the control benchmark for track operation and maintenance of existing lines,it provides a reliable guarantee for the smoothness and comfort of train operation.According to the actual situation in the operation and maintenance stage of Jiao-Ji Passenger Dedicated Line,and on the basis of introducing the construction of the line horizontal control network and vertical control network,this paper puts forward a precision measurement method and technical measures suitable for the reconstruction of the existing line track control network(CPⅢ),and analyzes and evaluates the measurement results.This achievement provides technical support for the follow-up track maintenance of existing operation lines.
