摘　　要：通信GSM-R系统是高铁行车控制和指挥的重要系统。在山区多隧道高铁线路,隧道内GSM-R无线信号覆盖通过敷设漏泄电缆完成,两隧道之间距离较短的区段采用漏泄电缆延伸信号覆盖方式较采用基站或直放站加杆塔方式简单可靠,而且可以减少无线信号小区切换频次。漏缆延伸敷设需建立辅助杆并利用接触网杆。为满足专业间规范要求,减小安全风险,对高铁线路漏泄电缆辅助杆设置方案进行合理优化有着重要意义。GSM-R communication system is a critical system to traffic control and command of high-speed railway.In mountain tunnel of high-speed rail line,the coverage of GSM-R wireless signal is completed through laying leaky coaxial cable.Compared with base station or repeater station tower,using leaky cable to extend signal coverage is more simple and reliable for the section where the distance between two tunnels is too short so that the switching frequency of wireless signal cell can be reduced.Auxiliary rod is required for laying leaky cable and the contact net rod should also be utilized.In order to meet the professional requirements and to reduce the safety risk,it is significant to optimize the setting scheme of leakage cable auxiliary rod of high-speed railway line.
