Research On The Construction Method For The Risk Warming System Of High-Speed Railway In The Difficulty Dangerous Mountain Area

For a long time, Safety is the eternal theme in railway transportation system, With the rapid development of national economy,technology and comprehensive strength, railway undertaking has got rapid development.Nowdays,it is on the way to be high speed, high density, high load and high technology, so there are new challenges on railway safety problems, especially in the western mountains. Due to the physical feature is perplexed and the physical environment is easily hurt,it is more difficult for railway building, operating, saveing,So the safety system of railway transport is facing more and more new demands and challenges. Therefore,.no matter to guarantee the safety of railway operation,or to improve it’s economic benefit and social benefit, to promote the progress of railway efficient and sustainablely,it is worth of great theory and realistic meaning that strengthening the Studing on the theory and method of the risk warning system of railway traffic.According to the need of safe transport on High Speed Railway in difficult Mountainous, relying on the scientific research project of China Railway Group Limited "the research of high speed railway rescue system",there are crarrying out the researching of work as following:Firstly, this thesis Analysised the current situation of Chinese railway industry,put forward the active demand of strengthening railway safety management.Researching on the Theory and application of risk warning system, contrasted and Analysised the shortage in our country’s safety management work. Aiming at this problem,this thesis puts forward the main researching contents and technical route.Then, this thesis puts more efforts into the physical feature,environment,economy,and the Current situation of the traffic development,the characteristics,safety and accidents of high-speed railway.puts out the the principle, theoretical framework and operation process of designing of risk warning system. In the risk identification subsystem, Seizeing the innate character of the reason of railway traffic accidents, in the view of the person-machine-environment system, explain the reason of railway accident, establish a safety evaluation index system.in the risk evaluation subsystem, innovatively using the fuzzy comprehensive evaluation method improved by rough set to realize evaluation efficiently and accurately. In the risk warning discrimination subsystem and risk warning countermeasure subsystem, it divises the the range of risk warning reasonably, learning from the eather forecast, warns by outputting signal intuitionally and guides the relevant departments to select the correct warning countermeasures.Finally, As the Western Railway "passenger line of Guiyang-Guangzhou" as an example, in connection with the tunnel fire accidents, in order to realize the useful value, it applied the model of safety management of high speed railway in the mountain area to the using.
