摘要
建立了车桥动力分析的空间模型 ,分析了高速铁路南京越江工程桥梁方案 40 0～ 80 0m钢斜拉桥在高速列车通过时的车桥动力响应。结果表明 ,只要桥梁结构设计合理 ,考虑的几种方案都是可行的。
In this paper, a 3-D dynamic analysis method of the train-bridge is established, it is used to calculate the dynamic response of the high-speed train and the long-span cable-stayed bridge crossing the Yante River. The results show that the schemes designed are mainly safe for the train and bridge, and comfortable for the passengers. In addition, some problems in the design of large span bridges are also put forward.
