摘要
统计了发生在唐山大地震中的 2 72座铁路桥梁的破坏概率。对唐山大地震和海城地震中 5 6座遭受地震破坏的桥梁按结构构造特征进行了分类 ,分析出各种构造特征对结构易损性的贡献率。描绘出了铁路桥梁在不同烈度地震作用下的破坏概率累积曲线。提出了一种简单的预测铁路桥梁地震震害的方法。
Damage probability of 272 Railroad Bridges in Tangshan earthquake is calculated. 56 bridges damaged in Tangshan and Haicheng earthquakes are classified according to their structural features. For each kind, contribution of the structural features to structural vulnerability are analyzed. Damage probability curves are drawn based on different seismic intensity. A simple method to predict earthquake damage to railroad bridge is proposed.
