摘要
如何评估汽车撞击对桥梁产生的安全影响是一个非常重要的问题。对汽车撞击城市立交桥墩后造成的桥墩受冲击动荷载进行力学分析,得到汽车的冲击力、桥墩的顶位移和破坏的临界力,对城市桥梁下部构造设计、桥梁维修、加固、桥梁荷载分析等,具有一定的参考价值。
It is important to evaluate the security of bridge pier that was crashed by the truck. By analyzing on dynamic load acting on bridge pier as it being crashed, the wallop of vehicles, peak displacement and critical power of destruction can be got, which are good reference for structure design of bridge bottom, maintenance, consolidation and load analysis of bridge.
