摘　　要：近些年来,我国高速铁路里程不断增加,高速铁路网络逐渐完善,进一步促进了我国经济的平稳发展。但高速铁路在运营期间由于外界环境变化及人为等不利因素的影响会引起高铁桥涵和路基的沉降和变形,威胁高速铁路列车运行安全,并可能导致灾难性事故的发生。本文以某高速铁路济南段范围内轨道复测实践,探讨高速铁路轨道控制网复测技术,研究现场实际轨道控制网的布设、测量和应用,并对部分轨道控制网显著变化区段进行分析,以期为今后轨道控制网复测积累经验。In recent years, China＇s high-speed railway mileage is increasing, high-speed railway network is gradually improved, further promoting the stable development of our economy. However, the settlement and deformation of bridges, culverts and roadbeds will be caused by the adverse factors such as environmental changes and man-made factors during the operation of high-speed railway, which threatens the safety of high-speed railway train operation and may lead to catastrophic accidents. Based on the practice of track retesting in Jinan section of a high speed railway, this paper discusses the retest technology of track control network of high speed railway, and studies the layout, measurement and application of actual track control network in the field. In order to accumulate experience for orbit control network retest in the future, the significant changes of part of orbit control network are analyzed.
