The Study Of Safety Warning In The Construction Of The Existing Line Electrification Project

The existing railway electrification reconstruction engineering is one of the important components of railway engineering in china. Because of the railway electrification project construction involves longitudinal multiple technical fields, the technology crossover, complexity and particularity of the construction environment, decide the high risk of the railway electrification construction. There are several accidents in the railway electrification construction process, although the accident reasons vary, but most are caused the personnel or economic loss. because the safety accidents occurred frequently, caused heavy losses to national economy and people’s safety and property, so research on the early warning of safety accident is particularly important.Through the research of the early warning theory, first of all, analysis the construction safety current situation of the existing electrification reconstruction engineering, pointed out the importance of research the safety of existing railway line electrification reconstruction and the existing problems. Secondly, from the four aspects of unsafe human behavior, the insecurity factors, adverse environmental condition, unsafe management that impact the safety of existing railway electrification reconstruction engineering, analyzed the safety risk factors in railway electrification reconstruction engineering construction, and analyze influence of man, machine, environment, management in the typical accidents. Finally, on the basis of analysis, combined with the safety situation of existing railway electrification reconstruction engineering, put forward the safety early warning research ideas of the existing electrification reconstruction engineering, from the four aspects of man, machine, environment, management build the security early warning index system, and puts forward the application of multi-level fuzzy evaluation method on safety warning indicator for evaluation, obtain result of early warning, adopt corresponding countermeasures to the unsafe state.
