摘　　要：高速铁路海底隧道GSM-R覆盖是设计和建设中的难点。以广湛高铁湛江湾海底隧道为例,研究高铁海底隧道GSM-R覆盖方案,分析分布式基站和数字直放站覆盖方案的优缺点,并提出海底隧道内设备安装方案,为今后高速铁路海底隧道GSM-R覆盖方案提供理论指导及工程参考。GSM-R coverage of high-speed railway undersea tunnels is a difficulty in design and construction.Taking Zhanjiangwan undersea tunnel of Guangzhou-Zhanjiang high-speed railway as an example,this paper studies the GSM-R coverage schemes of this high-speed railway undersea tunnel,analyzes the advantages and disadvantages of the coverage schemes of distributed base stations and digital repeaters,and puts forward the installation scheme of equipment in the undersea tunnel,providing theoretical guidance and engineering reference for the GSM-R coverage schemes of high-speed railway undersea tunnels in the future.
