摘　　要：水面对电磁波反射严重,导致水面无线信号较为复杂,且水面难以建设通信基站,因此铁路长大水面GSM-R无线覆盖已经成为铁路建设的难点。以南沿江城际铁路滆湖大桥为例,提出4种GSM-R无线覆盖方案,分别为桥头两端基站方案、湖心岛增设基站方案、桥上漏缆补强方案和桥上天线补强方案,并从网络覆盖效果、运营维护难度和投资大小等方面对各个方案的优缺点进行分析,最后提出南沿江城际铁路滆湖大桥采用的建设方案,供今后高速铁路跨越长大水面GSM-R系统无线覆盖借鉴参考。Due to the serious reflection of the water surface to electromagnetic wave,the wireless signal on the water surface is more complicated,and the communication base station cannot be built on the water surface.Therefore,the wireless coverage of GSM-R has become a difficult problem in railway construction.Taking Gehu bridge of Nanyanjiang intercity railway as an example,this paper puts forward four kinds of GSM-R wireless coverage solutions,including base station antenna scheme at both ends of the bridge,additional base station scheme at the island,bridge leaky cable reinforcing scheme and bridge antenna reinforcement scheme,and analyzes the advantages and disadvantages of each scheme from such aspects as the effect of network coverage,operation and maintenance difficulty and investment size,finally,it proposes the construction scheme of Gehu bridge of Nanyanjiang intercity railway,which can be used as a reference for wireless coverage of GSM-R system across the long water surface of high-speed railway in the future.
