摘　　要：由于高速铁路对桥梁竖、横向刚度要求较高 ,过去的桥梁设计方法已不再适应其需要 ,公铁两用桥则在构造上呈现公路与铁路桥梁的优势互补。为考察公铁两用大跨度桥梁在高速铁路上的适用性 ,本文分别选取我国自行研制的时速 2 0 0km·h- 1 的动力集中式电动车组和德国ICE高速列车 ,在相应的线路条件下 ,分析了高速列车通过芜湖长江大桥时的车桥耦合振动响应 ,说明该桥作为公铁两用桥 ,其结构特点保证了它具有较大的竖、横向刚度 ,能够满足高速列车运行的安全性及舒适性 ,并建议在各类交通规划时应当充分考虑公铁两用桥方案。High speed railway has relatively higher demands for rigidity of bridges. The past design method of bridges is outdated. But Highway railway Bridge appears to suit both highway bridge and railway bridge. In order to investigate whether the long span highway railway bridge is suitable to high speed railway or not, the paper chooses two kinds of high speed train, one Chinese and one German (ICE) to analyze dynamic interaction response between high speed train and bridge under railway conditions. According to the analysis, Wuhu Yangtze River bridge is considered to have enough vertical and lateral rigidity to meet the demands of high speed train. When we make various kinds of communication plans, the paper suggests that the highway railway bridge solution be considered.
