动态检测数据在高铁有砟轨道线路维修中的应用

Application of Dynamic Detection Data in Maintenance of Ballasted Track Lines of High-speed Railway

通过分析综合检测列车检测高铁有砟轨道线路测得的动态检测数据,查找出线路病害,分析线路病害成因,并提出有针对性整治方案。结合连镇高铁某区段综合检测列车的检测数据,研究轨道质量指数(TQI)在线路养护维修中的应用,为高铁有砟轨道线路维修工作提供辅助决策。

Through the analysis of the dynamic detection data of the comprehensive detection train in the process of detecting the ballast track of high-speed railway,the line disease is found out,the cause of the line disease is ana⁃lyzed,and the targeted remediation plan is put forward.Based on the dynamic detection data of a section of Lianyun⁃gang-Zhenjiang high-speed railway,the application of track quality index(TQI)in line maintenance is studied,which provides auxiliary decision for the maintenance of ballasted high-speed railway lines.
