Research On The Quality And Safety Risk Analysis Of Steel Structure Engineering Of Railway Station Building

The railway station is a city name card, is displayed outside the window of the city and the degree of civilization of the city as a landmark building is located. With the implementation of the "long-term railway network plan", the high speed railway development as the guidance, the country has built a number of new railway station project, the building modelling is exquisite, complete function layout, traffic flow is smooth, seamless, closely integrated with the urban traffic. The steel structure has the advantages of high strength, light weight, good toughness, plasticity and good seismic performance, factory production, convenient assembly, high construction speed, beautiful appearance, widely used in railway station construction. However, the steel structure engineering of railway station, has the advantages of novel modelling, complicated structure, numerous nodes and high technical content, the construction is difficult and complex construction environment, construction quality and safety in the process of risk factors, control more difficult, high risk and the need to further strengthen the quality safety risk management.The author through to the railway station building steel structure engineering quality safety risk management at home and abroad and research on the related literature and research results, using the Delphi method and checklist method to identify the main railway station building steel structure engineering quality and safety of the heavy difficulty and risk factors of risk.On the basis of risk analysis, sum up the railway station building steel structure engineering quality safety risk index system, including personnel risk, equipment risk, material risk, environment risk and method of risk, build the railway station building steel structure engineering quality and safety risk evaluation model, rich and detailed the unit engineering quality safety risk management theory.Using fuzzy analytic hierarchy process, to evaluate the risk of the construction of railway station steel structure engineering quality and safety risk assessment model. Through the beijing-shanghai high speed railway station of Tianjin-west railway station roof steel structure engineering case analysis and calculation, to verify the railway station building steel structure engineering quality and safety risk assessment model is scientific and feasible. And in view of the risk assessment results, puts forward the corresponding strategy and risk prevention and control measures, for the future railway station building steel structure engineering quality safety risk management provide certain reference and guidance.
