摘　　要：随着近年来中国高速铁路的蓬勃发展以及普速铁路的升级换代,GSM-R在中国铁路通信系统中发挥着越来越重要的作用。网络优化作为GSM-R工程建设的重要环节,直接影响网络覆盖合格与否。文章以磁东线铁路工程施工为例,对GSM-R网络测试中发现的典型问题进行了梳理分析,给出了相应的解决对策,并对网络优化技术经验进行了归纳总结,为类似的工程问题解决提供相关参考。With the vigorous development of high-speed railways in China and the upgrading of ordinary speed railways in recent years,GSM-R plays an increasingly important role in China's railway communication system.Network optimization,as an important link of the construction of GSM-R projects,directly affects the eligibility of network coverage.Taking the construction of the Cidong line Railway Project as an example,this paper analyzes the typical problems found in the GSM-R network testing,provides corresponding solutions,and summarizes the experience of network optimization technology,providing relevant reference for solving similar engineering problems.
