既有线提速综合检测技术研究与应用

Study and Application of the Comprehensive Inspection and Testing Technologies for the Speed-up Lines

通过对国外高速综合检测技术分析,为保障既有线提速200～250km/h列车运行安全,确保提速线路基础设施良好,研制了轨道几何状态检测、弓网检测、动力学检测、信号检测、ATP监测、无线场强检测、动应力测试和环境监视系统,自主集成200km/h过渡综合检测列车,并对京沪线等既有提速干线进行每十天一周期的动态实时检测和分析,提出尽快完善高速轨道动态检测评价标准及方法、深化接触网检测评判标准研究、尽快完善信号动态检测标准、形成我国铁路高速铁路动态检测标准体系等建议。

To guarantee the good performance of the infrastructure on speed-up lines,technical personnel develop systems including track geometry measuring,ATP monitoring,radio measuring of field strength,dynamic stress testing,etc.. Meanwhile,they integrate the 200km/h comprehensive inspection car independently,make real-time measurement and analysis of track geometry on speed-up lines like Beijing-Shanghai line,and put forward suggestions about perfecting assessment standards and methods of dynamic high-speed rail inspection,as well as establishing standard system for dynamic inspection of China high-speed lines.
