英文摘要：
The risk management is necessary for underground projects. This paper presents a review on the basic concept, process and effect of risk analysis briefly. Combined with the characteristic of the underground projects, the uncertain factors and destroy mechanism on the tunnel and underground cavern group are introduced. As the core of risk analysis, the risk assessment is discussed stressfully. At the same time, the method for carrying out the exact risk control and risk management based on the risk assessment is introduced. This paper further discusses the problems to be solved and the future development needs on the risk assessment methods.
