High-speed Railway Security Risk Management And Control

With the rapid economic and social development of our country’s high-speed railway, its efficient, comfortable, convenient, environm ental advantages, gradually becom e China’s important passenger transport mode. Therefore, the problem of high speed railway operation safety management becomes the focus of attention. Among them, the security risk management and control of high speed railway is an important part of the research on this problem, pay attention to. Therefor e, in this paper the most important safety risk assessment and risk control research in risk m anagement, in order to provide better support for the safety of high-speed Rail development.Based on this, th is paper made the f ollowing work: on e is the sys tem to stud y the security risk theory, high speed railway safety risk, and explore the content and basic method of safety risk m anagement, and introduces the high-speed railway safety risk, the operation process of the risk of electricity, traffic, public works to identify and prevent, combining with the characteristics of high speed railway, put s forward the suitab le for high speed railway safety risk management attention points; Second, on the basis of chaos theory, the high speed railway safety risk m anagement in an im portant part of security risk assessm ent, safety risk frequency prediction problem into the prediction problem of chaotic sequence, by calculating the best embedding dimension m, best delay tau, the reconstructed phase space, and calculate the corresponding maximum Lyapunov index, proved its high-speed rail safety risk frequency characteristics of chaos, in turn, using RBF ne ural network is forecasted, get a good harvest; Three is to build a high-speed railw ay safety risk index system, through the existing railway accident hierarchies, in full reference to the characteristics of high speed rail system on the basis of man, machine, ring, management, put forward four comprehensive indexes, and gives the corresponding quantit ative calculation m ethod, based on this, further explores the high-speed railway safety risk inten sity forecast, and connecting with th e security risk level prediction method, combined with the security risk frequency, realizing the high-speed railway security risk rating decision, provide support for the future study; Four is on t he basis of the former three parts, and put forward the corresponding security risk m anagement mechanism and the corresponding management information system.The work of the advanced com bination of theory and practice, th e application of historical data in th e evaluation of safety risk in hi gh speed railways, and played a good effect.
