本文根据对青岛市123座桥梁的考察结果,建立了与青岛市桥梁类型比例相当的国内243座桥梁的资料,并以此为对象阐述了城市桥梁震害预测因子法的研究过程,确定了桥梁易损性影响因素及其取值,给出了桥梁震害预测指标计算方法和各种破坏状态的划分依据等。最后将此方法运用到青岛市地震应急指挥系统中,对青岛市的123座桥梁进行了桥梁震害模拟。 Based on the survey results of 123 bridges in Qingdao, this paper establishes the data of 243 bridges in China which are equivalent to the types of bridges in Qingdao. Based on this, the research process of the earthquake damage factor of urban bridges is expounded, and the bridge The influencing factors of vulnerability and their values ​​are given, and the calculation methods of earthquake damage index and the division basis of various damage states are given. Finally, this method is applied to the earthquake emergency command system of Qingdao City, and the bridge damage simulation of 123 bridges in Qingdao City is carried out.
