摘要
朔黄铁路作为我国西煤东运第二大通道,承载着国家能源集团煤炭运输的重要任务,铁路基础设施投用时间较长,列车运行密度大,线路设备检修难度大,需要投入的人工成本不断增加.为缓解上线检查压力,运用探地雷达技术空耦采集方式对路基浅层病害进行快速检测,根据检测出的各类路基浅层病害B-Scan波形特点确定病害类型,查找病害位置,实现对路基浅层病害快速普查,精准指导现场设备维修.
Abstract
As the second largest channel for the transportation of coal from the west to the east in China,Shuohuang Railway carries the heavy responsibility of CHN Energy for coal transportation.Due to long-time operation of the railway infrastructure,high train operation density,and the difficulties in the line equipment maintenance,the labor costs that need to be invested are constantly increasing.In order to relieve the pres-sure of on-line inspection,ground penetrating radar(GPR)technology is used to quickly detect shallow sub-grade defects.According to the characteristics of B-Scan waveforms of all detected shallow subgrade defects,the defects can be determined of the types and positioned,so as to realize rapid inspection of shallow sub-grade defects and accurately guide the field equipment maintenance.
