摘要: 高速铁路轨道必须保持高平顺性、高稳定性和高可靠性,这直接关系到高速列车高速、安全且平稳运行。高速铁路轨道测量至少包括控制测量、线路测量和变形测量等工作。传统高速铁路轨道测量方法存在测量周期长、维护成本高、检测效率低等问题。为此,本文提出了一种基于全球导航卫星系统(global navigation satellite system,GNSS)/惯性导航系统(inertial navigation system,INS)多传感器组合的高速铁路轨道测量方法,并研制了相应的轨道测量系统。本文详细介绍了其主要构成和方法流程,并在实际高速铁路轨道精调工程中进行了应用示范。结果表明:该系统实现了轨道路基变形监测和高速铁路轨道不平顺绝对测量与相对测量的一体化,其轨道横向偏差精度2 mm、垂向偏差精度2 mm,变形点水平方向精度1 mm、垂直方向精度1.5 mm,显著提高了测量效率。

Abstract: High-speed railway tracks must maintain high smoothness, high stability and high reliability, which is closely related to the high speed, safe and smooth running of high-speed trains. High-speed railway track measurement at least involves control survey, route survey, and deformation survey. Conventional high-speed railway track measurement method has the weaknesses such as long measurement cycle, high maintenance cost, and low detection efficiency. To this end, a novel track measurement system based on global navigation satellite system (GNSS)/inertial navigation system (INS) and multisensor for high-speed railway is proposed, and corresponding track measurement system is developed. This paper systematically introduces the main components and the process procedures of the track measurement system, and it has been applied in the actual high-speed railway track fine adjustment engineering and the results show that the proposed solution realizes the integration of the track subgrade deformation monitoring and the track irregularity absolute measurement and relative measurement for high-speed railway with 2 mm lateral deviation accuracy and 2 mm vertical deviation accuracy of track, and 1 mm horizontal accuracy and 1.5 mm vertical accuracy of deformation points, which significantly improves the measurement efficiency.

Key words: engineering surveying, high-speed railway, track irregularity, deformation monitoring, global navigation satellite system (GNSS)/inertial navigation system (INS)
