对我国破坏性地震中的桥梁震害进行了详细分析,按照桥梁的结构形式、地震影响烈度、破坏部位、破坏部位的数量、破坏等级等进行了分类统计。应用概率统计和定性比较分析两种方法,得出了不同地震烈度下,桥梁破坏部位、出现概率和破坏等级呈现的规律;采用桥梁的破坏等级和破坏部位两种标准评价地震烈度,给出了基于桥梁震害评定地震烈度的建议指标。 The damage of bridge in China’s devastating earthquake was analyzed in detail, and the classification statistics were made according to the structure of the bridge, the intensity of earthquake impact, the damaged parts, the number of damaged parts and the damage grade. By using the methods of probability statistics and qualitative comparative analysis, the law of appearance probability and failure grade of the bridge under different seismic intensity is obtained. The seismic intensity is evaluated by two kinds of criteria, namely the damage grade and the damaged part of the bridge. Suggestion Index for Seismic Intensity Assessment Based on Bridge Damage.
