Research On Risk Management Of Construction Safety Of Railway Electrification Transformation Projects

ABSTRACT:In recent years, with the rapid development of electrified railway, the railway electrification transformation project has increased. The railway electrification transformation project has the characteristics of complex organizational relations, diverse and complex construction environment. And there are many uncertain risk factors in the railway electrification construction process. All these lead to a particular high probability for all kinds of safety accident. Carrying on the risk management of construction safety in the process of the railway electrification construction, it benefits the scientific decision, reducing the accident happening possibility, and taking a good control for the loss during perils. This paper takes the security risks of the railway electrification project construction as the research object, studies it with the qualitative and quantitative methods. Firstly, combining the characteristics of railway electrification transformation project, analysis the affecting factors from personnel, materials, equipment, the natural environment, the organization collaboration and so on, then identify safety risks of railway electrification transformation project construction. Secondly, establish the assessment model of safety risks of the railway electrification transformation project construction. The model considering the possibility of risk occurs and risk consequences, which use the fuzzy comprehensive evaluation method for risk assessment. At last, the paper give the analyses of the railway electrification transformation project construction safety risk strategy and the preliminary construction safety risk monitoring early warning management system. And the authors suggest supporting the safety risk management of the railway electrification transformation project construction from the risk management concept, organization, technology, manager, system, laws and regulation and so on.
