Abstract Compared with other kinds of tunnels and underground works, the subsea tunnel has the features of high complexity, uncertainty and high risk. To ensure the successful construction of a subsea tunnel, this paper systematically analyzed the mechanism for risk occurring in the whole process of subsea tunnel construction, presented the concepts of risk accumulation and risk assessment for the whole process of subsea tunnel construction. The main risk factors were analyzed and identified in terms of subsea tunnel planning, feasibility study, prospective design, bidding and tendering, construction and operation. Based on risk analysis, appropriate risk control measures were presented and successfully applied in the Jiaozhou Bay subsea tunnel in Qingdao.
