Affected by factors such as huge size and complex geological conditions, the super-large anchorage caisson foundation has high quality and safety risks in the construction stage. In order to assess these risks accurately, the work breakdown structure-risk breakdown structure (WBS-RBS) method, combined with expert investigation, was used to identify risks in the whole construction process. Based on the breakdown structure, an initial risk breakdown matrix was determined by estimating probabilities and corresponding loss levels of risk events. By analyzing weights of all kinds of risks through fuzzy analytical hierarchy process (FAHP), the result of the risk breakdown matrix was revised. Finally, the risk levels were divided according to the revised risk matrix values. As a case study, the proposed method was applied to construction risk assessment of the north anchorage caisson foundation of Wufengshan Yangtze River Bridge in Lianyungang−Zhenjiang high-speed railway. The results reveal that 158 risk sources were identified by the WBS-RBS and expert investigation method. Based on calculation of initial risk values and comprehensive weights, 16 major risk sources with the revised risk value larger than 1.696, such as caisson sudden sinking and attitude deviation were obtained according to the risk classification criterion. Besides, countermeasures such as special construction scheme, real-time construction monitoring, and reserved risk plan were provided. The research work provides a basis for the construction risk control of the open caisson foundation project and also provides a reference for the risk assessment and control of similar projects.
