摘要：Combined with navigation safety measures such as navigation mark adjustment, synchronous flash distribution, and real ship test adopted by Nanjing Yangtze River Bridge, theoretical analysis methods and data analysis are used to determine the safety evaluation risk index system, and an unascertained measure evaluation model based on entropy weight is constructed. Through the comparison of the effectiveness of the security measures analyzed by the questionnaire, the effectiveness of the bridge safety guarantee measures was evaluated; further suggestions on the optimization of relevant safety protection measures were proposed. The research results are of great significance for maintaining the safety of the bridge, the navigation order of the waters in the bridge area, protecting the navigation resources of the bridge area, and ensuring the navigation safety of the ship.
