摘要:
为分析栈桥结构的抗撞能力，研究了在车辆撞击作用下栈桥的结构反应及破坏机理．基于工程事故调查结果，对某火电厂输煤栈桥被车辆撞击的反应进行了数值模拟，分析了蜂窝梁和牛腿在车辆撞击作用下的破坏模式、应力及位移响应．计算结果表明：在撞击荷载作用下，蜂窝梁在支座及撞击部位应力最大；牛腿混凝土处于拉扭复合受力状态．分析结果可为车辆与栈桥碰撞问题提供参考．
Abstract:
In order to improve the capacity of collision of trestle structure, the mechanism of collision between truck and trestle structure was studied. Based on actual accident investigations, a classical collision accident of a coal transporting trestle hit by vehicle was simulated. The failure modes，stress and displacement response of the castellated beam and the bracket were analyzed. Results indicate that under impact load the stress of castellated beam was maximal at the supporting regions and impact site. Bracket has the feature of tension-torsion. The computational results can be used for further studies on the truck- trestle impact problem.
