| 摘 要： | 超高车辆和立交桥梁之间的碰撞事故屡见不鲜，深入研究车一桥碰撞机理，为提出车一桥碰撞桥梁损害计算方法奠定基础，具有重要的现实意义。基于高性能非线性有限元，对超高车辆一立交桥碰撞进行了高精度仿真分析，并对不同车速导致的桥梁损害情况进行了讨论。分析结果可为深入研究车一桥碰撞问题提供参考。

| Abstract: | Accidents of impact between over-high trucks and viaducts happen frequently. Detailed study on the mechanism of truck-viaduct impact is important for setting up the computational method of impact. In this paper a high precision simulation is presented for the truck-viaduct impact based on high performance nonlinear finite element analysis and the influence of truck speed to the damage of the bridge is discussed. The computational results can be used for further studies on the truck-viaduct impact problem. |
