摘　　要：为客观、快速预测受地震影响时桥梁的震害状态,借鉴同济大学朱美珍教授提出的桥梁震害预测经验模型及其震害预测指标系数值,对东莞市松山湖区既有4座桥梁进行了震害分析,得出了它们在遭遇地震烈度VII度、VIII度、IX度时的震害情况,结果比较合理。In order to predict the seismic damage of the bridges fast and objectively, this paper adops the seismic damage prediction model and index factors of bridges proposed by ZHU Meizhen, professor of Tongji University. Based on this model, the paper dose the seismic damage analyses for the 4 bridges located in Songshan Lake district in Dongguan city, and gets the damage case of the 4 bridges with three seismic intensities,i.e. VII, VIII and IX degree. The results obtained from the seismic damage analyses are rational and reliable.
