摘　　要：针对普速铁路车站高架改造引起的信号区间闭塞系统的技术改造,为降低既有线信号改造对铁路运输的干扰,保障铁路运营维护及施工作业人员的人身安全,结合信号系统区间闭塞电路原理及过渡工程设计经验,提出三种自动闭塞改造设计方案,详细描述不同方案区间闭塞设备具体设计改造内容,从施工条件、试验条件、工程工期、工程投资及运营安全等方面进行差异性对比分析,并根据工程设计不同的应用场景提出相应推荐方案,从而减轻既有线信号改造对铁路运输的影响,保障行车及人身财产安全。In response to the technical transformation of the signal section block system caused by the elevated transformation of normal-speed railway stations,in order to reduce the interference of existing line signal transformation on railway transportation,ensure the personal safety of railway operation,maintenance and construction personnel,combined with the principle of signal system section block circuit and experience in crossing engineering design,three automatic block transformation design schemes are proposed,and the specific design and transformation content of section block equipment in different schemes is described in detail.Comparative analysis is conducted on differences in construction conditions,test conditions,project duration,project investment,and operational safety,and corresponding recommended solutions are proposed based on different application scenarios in engineering design,in order to reduce the impact of existing line signal renovation on railway transportation and ensure the safety of vehicles and personal property.
