摘 要： The great Hanshin Awaji earthquake has brought a large number of structural failure and destruction. One of them is the fracture of a bridge bearing part of the Nielsen bridge type. It is not expectant that the fracture occurs under ordinary static or dynamic loading, instead the fracture is probably resulted from very high stress due to unexpected dynamic mechanism or impact. In this paper, the three dimensional dynamic behavior of a bridge of the Nielsen bridge type was analyzed, when an impact occurred between the upper and the lower parts of the bridge bearing of that, which might be caused by the great Hanshin-Awaji earthquake. The obtained numerical results show that a high stress sufficient to lead to a fracture occurs in the upper part of the bridge bearing, when an impact of velocity higher than 5 m/s occurred between the upper and the lower parts of the bridge bearing.

这种断裂并非由常规的静态或动态荷载引起，而是很可能由于突发的动态机制或冲击作用导致极高的应力而产生的。数值模拟结果表明，当桥墩上下部之间发生速度超过5米/秒的冲击时，桥墩上部会出现足以导致断裂的高应力。
