摘要
研究目的:随着列车运行速度的不断提高,灾害对列车运行的影响越发明显,同时灾害来临时留给司机的判断、反应时间也非常短,靠司机人工控车难以躲避灾害的影响。为最大限度地减小自然灾害等因素引发的列车行车事故、确保旅客生命和财产安全,必须设置灾害监测系统。上跨铁路的道路桥梁的异物侵限监测就是该系统的重要组成之一。本文结合典型的多线并行公跨铁异物监测设置实例,提出具体的设计方案,详细分析并研究确定多线并行地段公跨铁异物侵限监测的构成、监测功能及系统设置等问题,供类似工程的设计、建设、改造和运营借鉴。研究结论:(1)多线并行区段设置公跨铁桥异物监测时,除遵守规范中的要求外,还应遵循故障-安全原则,并优先采用设备控制,确保行车安全;(2)设计时应进行充分地调查,按调度区域的划分,合理确认信号集中区分界,并考虑运营维护便利的需要,对分属不同运营维护单位的异物监测网分开设计;(3)针对不同厂家设备接口,应与各厂家充分进行技术沟通,制定出较为优化的连接方案;(4)本研究成果可应用于采用灾害监测系统的铁路工程设计和运营中,具有借鉴和指导意义。
Research purposes： With the train operation speed improved steadily, the impact of the disaster On the train operation is more obvious, the judgment time and reaction time for the driver while disaster comes to is also very short, so it is hard to avoid the impact of disasters by controlling the train manually. The natural disaster monitoring system must be set up to reduce the traffic accidents caused by natural disasters factors, and to ensure the safety of passengers＇ lives and property. The foreign object invasion monitoring of the road bridge which crosses over the railWay is one of the important components of this system. Based on the design example of typical foreign object invasion monitoring for bridge over multi- line adjacent area, this paper gave a specific design scheme, analyzed and researched to determine thestructure, monitoring functions and design of the system in detail which can provide reference for design, construction, alteration and operation of similar engineering. Research conclusions： （ 1 ） In order to ensure the safety of running, when designing a foreign object invasion system of the road bridge which crosses over multi - line railway, the fail - safe principle should be obeyed requirements from the code, and the equipment control should be prior made. （2） A thorough investigation monitoring besides the is required before designing the system and the boundary of the centralized interlocking area should be decided reasonably according to the dispatch area, and the foreign object invasion monitoring networks which belong to different divisions should be designed separately on the consideration of easy operation and maintenance. （3） It is important to draw out a scheme that is optimized based on the specific interface used through technical communication with the suppliers. （4） The research result has a strong reference and guidance for similar project, and can be applied to the engineering design and operation of the railway natural disaster monitoring system.
