摘　　要：车致桥梁损伤属于诸多桥梁应急事件中发生概率较高的一种。为了研究车辆导致的桥梁损伤及其检测评估标准,首先进行了车致桥梁损伤类型的划分,其次分别以装配式空心板桥、T梁桥及箱梁桥等常规桥梁为对象,在分析桥梁损坏特点及模式的基础上,提出了除车辆起火外车致桥梁损伤时相应的应急快速检测内容及流程,最后给出了桥梁损伤等级评估标准,可为桥梁安全事故的应急检测与评估提供参考。Bridge damages caused by vehicles is a kind of high probability of occurrence in bridge emergency. In order to research the damage caused by vehicles and its inspection and evaluation criterion,firstly,the classification of bridge damage types caused by vehicles was proposed in this paper. Then,the damage characteristics and patterns for regular bridges including prefabricated hollow-slab bridge,T-beam bridge,and box-girder bridge were discussed respectively, and the corresponding rapid inspection contents and flowchart were presented. The evaluation criterion of bridge damages except vehicles fired was finally proposed. The criterion can provide a reference for emergency detection and assessment of bridge safety accidents.
