【摘要】：长期以来,安全运输都是铁路系统永恒的主题,伴随着我国经济、技术、综合实力的日益提高,铁路事业也得到了突飞猛进的发展,目前正朝着高速度、高密度、高载重、高技术的方向发展,这给保证铁路运营的安全提出了新的挑战,尤其是在我国西部山区,地形地质复杂、自然环境比较脆弱,高速铁路的建设、运营、救援难度更大,使得铁路运输安全保障系统面临着更多新的需求和严峻的挑战。因此加强铁路安全预警理论与方法的研究,无论对于保证铁路运营的安全,还是对于提高其经济效益社会效益,促进铁路事业安全高效、可持续的发展,都具有巨大的理论和现实意义。本文根据困难艰险山区高速铁路安全运输的需要,以中国中铁股份有限公司科技开发计划的工程科研项目“困难艰险山区高速铁路救援系统研究”为依托,主要开展以下几个方面的研究工作：首先,分析我国铁路事业的发展现状,提出加强铁路运营安全管理工作的迫切需求,需要构建一个合理有效的安全预警系统。对国内外安全预警系统的理论和应用情况展开研究,对比、总结分析出我国安全管理工作的不足。针对此问题,提出本文的主要的研究内容和技术路线。其次,重点研究困难艰险山区的地形地貌、环境、经济、交通发展现状,高速铁路的特点、安全状态以及易发的安全事故,提出安全预警系统设计的原则、依据、理论架构以及操作流程。在安全风险识别子系统中,抓住铁路行车事故致因的本质,从人—机—环境—管理系统的角度,阐述铁路事故发生的原因,建立一个安全评价指标体系。在安全预警评价子系统中,创新性的使用粗糙集改进的模糊综合评价法高效准确的完成安全评价工作。在安全预警判别子系统中,合理的划分预警的区间,并借鉴“天气预报”的报警形式,选择直观的预警方式输出报警信号从而给相关部门做出指示以选择正确的预警对策。最后,以西部铁路贵广线铁路为例,针对隧道火灾事故,将所设计的理论模型应用到困难艰险山区高速铁路运营的安全管理工作中去,实现了本理论设计使用价值。
[Abstract]:For a long time, safe transportation has been the eternal theme of railway system. With the development of economy, technology and comprehensive strength of our country, the railway industry has also been developing by leaps and bounds. At present, it is moving towards high speed, high density and high load load. The development of high technology has brought new challenges to ensuring the safety of railway operation, especially in the mountainous areas of western China, where the topography and geology are complex, the natural environment is relatively fragile, and the construction, operation and rescue of high-speed railways are more difficult. The railway transportation safety guarantee system is faced with more new demands and severe challenges. Therefore, to strengthen the research of railway safety warning theory and method, not only to ensure the safety of railway operation, but also to improve its economic and social benefits. It is of great theoretical and practical significance to promote the safe and efficient and sustainable development of railway industry. According to the need of safe transportation of high speed railway in difficult and dangerous mountainous areas, this paper relies on the scientific research project "Rescue system Research of High Speed Railway in difficult and dangerous mountainous areas", which is an engineering scientific research project of China China Railway Co., Ltd. The main research work is carried out in the following aspects:. First of all, it analyzes the current situation of railway development in China, and puts forward the urgent need to strengthen the safety management of railway operation. It is necessary to construct a reasonable and effective security early warning system. The theory and application of security early warning system at home and abroad are studied and compared, and the shortcomings of safety management in our country are summarized and analyzed. The main research content and technical route of this paper are put forward. Secondly, it focuses on the study of topography, environment, economy, current situation of traffic development, characteristics, safety state and risk of accidents of high speed railway, and puts forward the principle and basis of the design of safety early warning system. In the subsystem of safety risk identification, we grasp the essence of the cause of railway accidents, and expound the causes of railway accidents from the point of view of man-machine-environment management system. A safety evaluation index system is established. In the security early warning evaluation subsystem, the fuzzy comprehensive evaluation method, which is improved by rough set, is innovatively used to complete the safety evaluation work efficiently and accurately. This paper divides the interval of early warning reasonably, and draws lessons from the warning form of "weather forecast", and chooses the direct warning mode to output the alarm signal so as to give instructions to the relevant departments in order to select the correct early warning countermeasures. Finally, taking the Gui-Guangzhou railway of the west railway as an example, the designed theoretical model is applied to the safety management of the high-speed railway operation in the difficult and dangerous mountainous areas in view of the tunnel fire accident, and the practical value of the theoretical design is realized.
