Abstract:
Risk management is an important task in railway construction project management. At present, there are many problems in the risk management during the construction of railway projects, especially in the aspect of safety risk management. Therefore, it is necessary to strengthen the risk management of railway construction projects. Firstly, the risk management of tunnels on ZhengzhouWanzhou Highspeed Railway in Hubei is introduced from the stages of survey, design and construction; the safety risk, natural risk and duration risk factors of the tunnel in Hubei are mainly identified by using the procedure and method of risk management. And then, the initial risk grade of the tunnels is proposed by estimating and evaluating the probabilities and consequence grade of the risk, and suggestions on the grade of risk management during construction are proposed. Finally, some risk control countermeasures, such as avoiding extremely high risks in line selection design, strengthening advance prediction and cooperating with largescale mechanized construction, are put forward according to different grades of risks.
Key words: highspeed railway tunnel, risk management, risk assessment, risk grade, control countermeasures
