Safety Risks Assessment Of Railway Electrical Renovation Construction Based On Fuzzy Influence Diagram

Railway electrical renovation construction mainly refers to the traction power supply system (catenary、traction、substation) engineering construction implementation stage of the production activities, to match the technical renovation of the station and yard, communication, signal, such as the power engineering project. In electrification construction, each professional construction most engaged in outdoor work, poor working conditions; Liquidity, operation, construction process to ensure that both internal and to ensure that the external (traffic, transportation, existing infrastructure) environmental security, not easy to management; Cross on the objective environment construction, along with complex. In the face of such unfavorable factors and conditions, do a good job in railway electrification construction safety risk management is particularly important. On the study of the theory of the railway electrification construction safety risk analysis, not only has important significance to improve the safety risk management theory, also can guide the construction practice, to ensure the construction target reached smoothly.Based on the railway electrification construction safety risk as the research object, adopt the method of fuzzy influence diagram study of a problem. First, combining with the characteristics of railway electrification construction, from the features of the railway electrification construction safety risk comprehensive system research; Then, from the aspects of personnel, material, environment and management of construction safety risk factors in the process of the comprehensive risk analysis; Then, by using the principle of the influence diagram, studied the formation process of railway electrification construction safety risk events, the influence of the relationship between risk factors and risk influence diagram is established, on the basis of building the railway electrification transformation based on fuzzy influence diagram construction safety risk evaluation model; Finally, the paper analyzes the railway electrification construction safety risk coping strategies, according to three main factors affecting the safe construction of the railway electrification control countermeasures are put forward, and gives the establishing railway electrification construction safety risk monitor early warning management system.
