摘要：针对高铁动车组列车进出动车段（所、存车场）的不同运营场景，对动车存车场内岔区侧向允许通过速度低于列控车载设备顶棚限制速度导致的列车紧急制动等问题进行了研究。通过对典型动车存车场内站场布置方案、道岔号码选择、信号系统设置情况进行分析，结合动车组列车进出动车存车场的特殊运营场景，分析了 CTCS-2 级列控车载设备在不同工作模式下存在的运行风险，即动车存车场内设置 9 号道岔时其侧向允许通过速度会对列车安全运行造成影响。在此基础上，根据新建和既有动车段（所、存车场）的不同情况提出了两种优化方案，优化后的方案已在部分工程中进行了应用，同时也为后续铁路的工程设计、运营维护提供了借鉴。
Abstract: For the operation scenario of MU trains entering and exiting the MU depot (stabling yard), a study was conducted on the emergency braking of trains caused by the allowable lateral passing speed at the switch zone of the MU stabling yard being lower than the onboard ATP ceiling restrictive speed. Through analyzing the station layout plan，turnout number selection, and signal system settings in typical high-speed train depots, combined with the special operational scenarios of MU trains entering and exiting high-speed train depots, the operational risks of CTCS-2 onboard ATP equipment under different working modes were analyzed. That is, when the No. 9 turnout is set in the MU stabling yard, its lateral allowable speed will affect the safe operation of the train. Based on this, two optimization schemes are proposed according to the different conditions of newly-built and existing high-speed rail MU depot (stabling yard). The optimized schemes have been applied in some projects, and also provide a reference for the engineering design, operation and maintenance of subsequent railways.
