In recent years, EPC mode has been developed rapidly in water conservancy projects. However, due to the complex construction conditions, long construction period and easy to be affected by natural conditions of water conservancy project, the general contractor of EPC project is faced with greater risks. If the risk analysis is not enough, the project profit of the contractor will be lower than expected or even loss. Water conservancy project risk indicators are qualitative indicators, which are easily affected by subjective factors and quantitative uncertainty in the process of index quantification. In this paper, combined with the relevant research at home and abroad, combined with the characteristics of water conservancy projects, the establishment of water conservancy project risk assessment level index system. The set pair analysis model which can comprehensively evaluate the connection degree between risk index and risk level and the entropy weight model which can reflect the information content of the index are introduced into the risk evaluation of EPC water conservancy project. The evaluation results show that the entropy weight method can calculate the weight of each risk index in the risk level, and the set pair analysis method can comprehensively evaluate the connection degree between the risk index and different risk levels.
