严寒地区高速铁路轨道分布式光纤安全监测研究

Study on Distributed Optical Fiber Safety Monitoring for High-speed Railway Tracks in Severe Cold Regions

基于严寒地区特殊的地理环境条件,研究了该地区高速铁路无砟轨道的损伤问题,并采用分布式光纤传感技术,构建了CRTSIII型板式无砟轨道全寿命周期的安全监测系统,分析探讨了该监测系统中各个监测对象的传感器布设及监测方法,为严寒地区CRTSIII型板式无砟轨道系统的长期安全运营提供技术支撑。

In this paper,the damage problem of high-speed railway CRTSIII slab ballastless track in cold region is analyzed,a safety monitoring system for CRTSIII slab ballastless track based on distributed fiber optic sensing technology is constructed,in which the sensor layout and monitoring methods of each monitoring object in the monitoring system are analyzed and discussed.This paper could be provided for monitoring techniques for the long-term safe operation of the CRTSIII slab ballastless track in cold region.
