摘要
With the vigorous development of inland river shipping economy,the trend of large ships passing Nanjing Yangtze River Bridge is obvious.The standard formula of ship collision force is selected by comparing the empirical calculation formulas.Four representative ship types are selected for calculation and analyzing of collision force.It is concluded that the anti-collision ability of the Nanjing Yangtze River Bridge does not meet the requirement of large ship collision force when the speed is more than 8-knots.From the perspective of active collision avoidance,this paper puts forward the navigation safety supervision countermeasures.A conceptual model of guided pulley anti-collision device is designed from the perspective of passive anti-collision.The research results provide references for safety supervision and anti-collision measures for the bridge.
