摘　　要：采用CTCS-2级列控系统的客货共线铁路,为兼顾普速列车和动车组开行,信号工程设计需要考虑若干特殊问题。结合典型工程案例,探讨站内采用不同制式轨道电路的场景下信号工程设计中涉及的问题。对站内采用25 Hz轨道电路且有多条线路引入的大型车站,分析存在的特殊码序问题,给出特殊码序追踪及码序衔接的建议方案;就咽喉区过长可能导致列控系统车载设备输出制动的问题,采用增设进路信号机和补码的处理措施予以解决;对站内采用一体化轨道电路的车站,分析将所属线路定义为普速铁路和高速铁路的差异性,并依据相关标准规范,从联锁表、码序表、列控工程数据等方面,分析和探讨信号工程的设计要点。对信号工程设计中特殊问题的分析及提出的解决方案,可为今后类似工程项目的信号设计提供参考。In view of the operation of both general speed trains and high-speed EMU trains on the passenger and freight mixed operation railway with the CTCS-2 level train conreol system,there are some special problems to be considered in signal engineering design.Combined with typical engineering cases,the problems of signal engineering design for the scenarios adopting different types of track circuits in stations are discussed.For large-scale stations using 25 Hz track circuit and with the introduction of multiple lines,the existing special code sequence problems are analyzed,and a recommended plan for special code sequence tracking and code sequence connection is given.In view of the long throat area resulting in the problem of braking output by the onboard ATP equipment, a routesignal is added and supplementary code is adopted to solve the problem. For the stations with integratedtrack circuit, the discrepancies between defining the involved line as general speed railway and highspeedrailway are analyzed and the key points of signal design are analyzed according to the relevantstandards and specifications from the aspects of interlocking table, code sequence table and train controlengineering data. The analysis of special problems considered in signal engineering design and theproposed solutions can provide reference for signal design of similar engineering projects in the future.
