Impact speed of vessel collision considering inland river channel characteristics
How to select the impact speed is one of the most import ant factors to determine ship collision force with the pier. It will directly influence the standard on anti-impact force in the bridge design. In this paper, the existed methods of determining impact speed in all countries and the examined examples of ship collision with pier are analyzed. Based on the limitation of existing method, a new way to determine impact speed is proposed which can consider the water flow velocity at every pier along bridge axial and influence of ship accident. Through application in AnQing Yangtze Railway Bridge, the reasonableness of the method is examined, which can provide references for bridge design in ship collision..
