| Of this magnitude railway project in construction process especially need to work together with project about the owner of the company, supervision unit and contractors specialized risk management.In this paper the Shanghai-Hangzhou railway passenger special line5section of full project on the base of investigation, with Chinese high-speed rail project risk management of the actual status and existing problems, and from the Shanghai-Hangzhou railway passenger special line5section of the construction phase project risk identification, risk assessment, risk control the three aspects of the project risk management makes a detailed analyses of the system in this paper.First of all, according to a certain method and process, to construct the project risk evaluation index system. Then, using triangle fuzzy Numbers, fuzzy comprehensive evaluation method and network with the method of analytic established based on fuzzy network analysis risk evaluation model, and the Jiadong river bridge construction risk evaluation. Finally, based on the principle of system construction thought and Shanghai-Hangzhou railway passenger special line5section of the construction of the project risk analysis of the specific factors and evaluation result, from BeiLei beam cast-in-situ concrete box girder by risk control measures, mass concrete risk control measures and economic and management risk control measures three aspects in detail the construction risk control.To sum up, this paper Shanghai-Hangzhou railway passenger special line5section of the construction of the project risk management process are some exploration and innovation, through the model for the evaluation result and the practice of risk control measures, get the evaluation model is established in this paper can be compared the results of the comprehensive and objective reflection of the project risk status, risk control system can be aimed at the evaluation of risk position, the effective control of the conclusion. |
