Abstract: The risk management standards on tunnels and underground works issued by different industries in China are different. The necessity to unify the risk management standards on tunnels and underground works in China is discussed in terms of enriching and popularizing the risk management knowledge, improving the risk management level, establishing standard risk management system on tunnels and underground works, boosting the development of project warrant and project insurance and speedingup the systemization and legalization of risk management. Advice is made on the risk management in terms of unifying the terms, risk classification standards, risk management procedures and risk management contents, by comparing the risk management standards on railway tunnels, highway tunnels and MRT works.

Key words: tunnel, underground works, risk management, standard unifying
