| 摘 要： | 根据美国阿肯色河桥和广东九江大桥船撞非通航孔桥墩时的速度,质疑美国公路桥梁设计规范中"船偏离航线速度正比下降"的方法。符合实际地总结出"失舵不失速"的工况,结合安庆铁路桥的防撞研究,对船撞桥速度的选取、船撞力和需设防桥墩数目的确定提出了见解,并对防撞方案进行了探讨。

| 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 Rive... |
