| 摘 要： | 桥梁在船舶碰撞时受到的动力荷载和响应是复杂的动力非线性问题。通过冲击动力学理论,利用有限元软件AN-SYS/LS-DYNA对忠县长江大桥在高低水位下的船舶撞击进行模拟,对船舶在高低水位下的碰撞情况进行对比,并将碰撞力数值与各种规范的数值进行比较,可为桥墩防撞系统的设计提供参考。

| Abstract: | Dynamic force load and response when ship impacts bridges is a complex dynamic force non-linear problem. Based on collision dynamic force theory,finite element software ANSYS/LS-DYNA is utilized to simulate the impacted Yangtze River Bridge in Zhong County under high and low water level. Meanwhile the impact situations under high and low water level are compared. What＇s more,the collision values are compared with those in the specifications. It can provide reference for designing the bridge pier anticollision system. |
