摘　　要：温岭—玉环铁路在温岭站附近与甬台温线、杭绍台动走线存在交叉并线区段,在温岭线路所附近与甬台温线、杭绍台线、甬台温至杭绍台上/下行联络线存在交叉并线区段。首先,根据温玉铁路设计标准确定GSM-R网络采用单网交织覆盖方式,分别从设计原则、网络覆盖方式及电平要求、重叠覆盖区及时延计算等方面进行分析;其次,对交叉并线区段的GSM-R系统网络覆盖方案进行研究,深入比较不同GSM-R系统网络覆盖设计方案的优缺点,从不同铁路列控等级、交叉并线区段路网类型两方面进行对比,分别为温岭站、温岭线路所交叉并线区段制定出详细设计方案;最后,通过专用仿真软件对基站覆盖有效电平、基站覆盖重叠区域进行模拟仿真。仿真结果表明,交叉并线区段GSM-R网络覆盖电平满足在95%的地点和时间统计概率下,接收机输入端最小可用接收电平不小于-92 dBm的要求,为确定类似铁路区段GSM-R网络方案提供借鉴。The Wenling-Yuhuan railway has cross and parallel sections with the train running line of Hangzhou-Shaoxing-Taizhou railway and Ningbo-Taizhou-Wenzhou railway near Wenling railway station.There are also cross and parallel sections with Ningbo-Taizhou-Wenzhou railway,Hangzhou-Shaoxing-Taizhou railway and the up/down connection line from Ningbo-Taizhou-Wenzhou to Hangzhou-Shaoxing-Taizhou railway near Wenling block post.Firstly,according to the design standards of the Wenling-Yuhuan railway,the GSM-R network was determined to adopt a single network interweaving coverage method.Analysis is conducted from the aspects of design principles,network coverage method and level requirements,overlapping coverage area and time delay calculation.Secondly,the network coverage scheme of GSM-R system in the cross and parallel sections is studied,deeply comparing the advantages and disadvantages of different GSM-R system coverage design schemes from two aspects:different levels of the train control system and network types.The detailed design schemes for the cross and parallel sections of Wenling station and Wenling-Yuhuan railway station are formulated respectively.Finally,the effective level of base station coverage and the overlapping area of base station coverage are simulated by special simulation software.The simulation results show that the coverage level of the GSM-R network in the cross and parallel sections meets the requirement that the minimum available reception level at the receiver input end is not less than-92 dBm with a 95%statistical probability of location and time,providing reference for GSM-R network schemes in similar railway section.
