为研究桥梁在超高车辆撞击下的受力状态,深入研究了车-桥的碰撞机理,采用了通用有限元程序ABAQUS,针对不同车速车辆垂直撞击桥梁的情况进行了模拟分析,分析表明,车速越大,主梁的应力和位移越大,主梁破坏的越早.

In order to study the stress state of bridge beam under the collision of ultrahigh vehicles with different speeds, the paper studies the collision mechanism of vehicle and bridge deeply, gets simulation analysis based on the general finite dement program ABAQUS and aiming at the situation of vertical impacting on the bridge of different vehicles with different speeds. Analysis shows that the higher the vehicle speed, the larger the stress and displacement of the main beam, and the earlier the main beam destruction.
