Abstract
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.
Highlights
Bridges play an irreplaceable role in promoting economic and social development
Through the analysis and evaluation of effectiveness, we can better understand and master the effectiveness of the safety and security measures implemented by the bridge, and provide scientific decision-making basis for the maritime management department to improve the navigation environment and traffic safety of the bridge section and the navigation management and control
This paper takes the various security measures adopted by the Nanjing Yangtze River Bridge as the research object, and uses theoretical analysis methods and questionnaire survey data to evaluate the implementation effectiveness of the bridge navigation safety guarantee measures for the navigation environment of the bridge area of the Nanjing Yangtze River Bridge, and analyze the Nanjing Yangtze River
Summary
In the event of a bridge safety incident, the consequences will be unimaginable. More and more bridges are built in the same jurisdiction. It is especially important to carry out the necessary safety guarantees for the safety of the bridge and how to properly solve the problem of water traffic safety in the bridge section. Safety evaluation of the safety measures implemented by the bridge is carried out, and corresponding countermeasures are proposed in time. Through the analysis and evaluation of effectiveness, we can better understand and master the effectiveness of the safety and security measures implemented by the bridge, and provide scientific decision-making basis for the maritime management department to improve the navigation environment and traffic safety of the bridge section and the navigation management and control. Having a certain practical value [1]
