Descrição: In recent years, there have been lots of ship-bridge collision accidents around the world, especially large sea-crossing bridges. Reasonable risk assessment of ship collision for sea-crossing bridges is an important guarantee for the safe operation of bridges. Through the investigation and analysis of ship-bridge collision accidents in recent years, multiple influencing factors leading to collision were determined and a hierarchical evaluation index system consisting of 4 secondary indicators and 18 third-level indicators was established. Based on the Analytic Hierarchy Process(AHP)and the Entropy Weight Method, the subjective and objective evaluation indicators were empowered to clarify the importance of various risk factors. According to the fuzzy theory, the risk of ship collision with sea-crossing bridge was evaluated comprehensively at multiple levels. As an example of sea-crossing bridge engineering, with the ship navigation statistics of a certain year, the risk assessment of ship collision with bridge
