Abstract: According to the velocity of ship collision with the non-navigable passage piers of the Arkansas River Bridge in U. S. and the Guangdong Jiujiang Bridge in China, the method proposed in American Road and Bridge Desig Code that the ship speed declines proportionally to the distance that the ship migrates from the shipping route is questioned. The conclusion that the ship velocity won＇t stall when ship loses rudder is brought forth thereafter. Combining with the anti-ship collision study on the Anqing Yangtze River Railway Bridge, several meaningful ideas are put forward for the speed selection and the confirmation of the ship collision force with bridge and the number of piers which need to be established for bridge anti-collision, and the discussion on the anti-collision scheme are also explored.

Key words: Anqing Yangtze River Railway Bridge , velocity of ship collision with bridge , ship collision force with bridge , equipment for bridge anti-collision ;
