The Study And Application Of Risk Assessment Ways For Special Purpose Railways

China railway transport undertakings have been developing rapidly, and the current, is heading towards "high-speed, high-loaded" world high level target continuously. But with this rapid development, its "safe" problem has also become a major issue, and needs state railway related departments to give more attention, to input more. As a part of the railway network---special purpose railway, seizes an important position in railway freight transport. Because of its own characteristics and development relations, special purpose railway's safety hidden trouble distributions much more. Thus, for special purpose railway, its safety problems must be taken stronger countermeasures.In the high-speed development process of railway transport undertakings, safety management mode's reform has made staggered results and outstanding performance, which gradually becomes "afterwards treatment" to "forwards prevention". To achieve this goal, risk assessment is one of the critical paths. Risk assessment technology was introduced to China in 1980s.After lots of practices since validation of production safety in China, risk assessment plays an effective role in every industry, and is more and more strengthened by the government. Among them, the risk assessment work of special purpose railway won the attention of the appropriate departments of railway and administration of production safety department, as well as the relevant laws, regulations and standards, etc.This article is developing upon the above background. For the risk assessment of the special purpose railway, whose research is not strong enough, less-systematic, so the article will try to explore appropriate methods and applications about the risk assessment of the special purpose railway.At first, the author describes from current situations of railway risk assessment both at home and abroad to the research background, research target and content. Then is the theory of risk assessment methods, which is prepared to introduce aspects of the risk analysis for special purpose railway. Next part is the research and practice about the risk assessment of special purpose railway. This part's foundation mainly derived from the safety railway management on the lines of Chengdu city railway department, and the actual participations of the risk assessment work for the special purpose railway. In this part, the common problems and common accidents of the special purpose railway are classified. In addition, the author analyzed some dangerous and harmful factors, combining the basic theory of identification of risk analysis, so as to establish the risk assessment model of the special purpose railway further. Moreover, the risk assessment's basic requirements and evaluation program of the special purpose railway is briefly discussed, as well as present risk assessment process control and quality management system. Based on the above things, the author establishes the assessment model. In order to specify the applications of the model, the paper gives an practical application example on the special purpose railway of the Shuicheng Steel Group. And at last, the author attains an risk assessment to guide the company of the special purpose railway.
