近年来,无缝线路应用已成普遍趋势,无缝线路检测一直是被关注的问题。简要介绍了营运期间无缝线路检测意义、目前无缝线路锁定轨温检测方法原理。以京津城际及京沪高铁位移观测桩设置方法为例,介绍了位移观测桩法在高速铁路中的具体应用,举例说明了位移观测桩法计算实际锁定轨温。
In recent years, the application of seamless line has become a general trend, and seamless line detection has always been a concern. Briefly introduced the meaning of seamless line detection during operation, the principle of the current seamless line lock rail temperature detection method. Taking the Beijing-Tianjin intercity and Beijing-Shanghai high-speed rail displacement observation set-up method as an example, this paper introduces the application of displacement observation pile method in high-speed railway, and illustrates the calculation of the actual locking rail temperature by the displacement observation pile method.
