Combining with the characteristics of submerged floating tunnel (SFT) and surrounding environment, it is of great theoretical and practical significance to develop research in the areas of potential risk and impact factors, risk index system, risk level of SFT. This paper summarized the main content of risk analysis of SFT, and classified the risk management into six stages: planning, feasibility study, design, tendering, construction and operation. Risk management workflow of SFT was given. Then, we focused on discussing the potential risks of SFT in investment, design, and environmental condition during planning and feasibility study stage. After identifying the risk factors of SFT, the risk assessment method of SFT was described by the presented fuzzy AHP method (FAHP). Finally, taking environment risks assessment of SFT prototype in Qiandao Lake as an example, environment risk assessment of SFT was completed by the programmed integration evaluation system of SFT based on Matlab7.5. Some measures and suggestions in risk control strategy were given.
