高速铁路隧道公网覆盖信号强度提升方案研究

Research on Signal Strength Enhancement Scheme for Public Network Cov-erage of High Speed Railway Tunnels

在山区高速铁路中,铁路隧道在铁路线路的占比较高,由于其特殊的地理环境和结构特性,铁路隧道内的移动信号覆盖问题一直是移动通信行业关注的重点。文章研究了高速铁路隧道公网覆盖信号强度的提升方案,通过对现有技术的梳理和分析,结合实例和统计数据,提出了多种可行的解决方案,并进行了详细的分析和评估。技术方案可为高速铁路项目的设计与施工提供有益的参考。

In mountainous high-speed railways,railway tunnels account for a relatively high pro-portion of railway lines.Due to their special geographical environment and structural character-istics,the issue of mobile signal coverage inside railway tunnels has always been a focus of atten-tion in the mobile communication industry.This article studies the improvement schemc of sig-nal strength for public network coverage of high-speced railway tunnels.Through sorting and an-alyzing existing technologies,combined with examples and statistical data,various feasible solu-tions are proposed,and detailed analysis and evaluation are conducted.The technical solution can provide useful references for the design and construction of high-speed railway projccts.
