| 摘要: |
| 进行了高速铁路南京越江方案中三塔斜拉桥的车桥耦合振动分析.分析采用有限元等数值计算方法,建立了车桥动力学方程.计算结果表明,三塔斜拉桥方案具有较好的动力性能,基本满足行车安全和乘客舒适性的要求.还指出,只要桥梁的自振频率远离列车的激励频率,按静力计算的桥梁横向和竖向刚度一般都能满足现有规定的要求. |

| Abstract: |
| This paper reports the vibration analysis of
the two main span cable-stayed bridge under the high-speed train crossing the Nanjing
Yangtse River. Such numerical methods as finite element method are used to found the
vehicle-bridge dynamic motion equati |
