| 既有线32 m下承式钢板梁加固方案的车—桥动力仿真分析(29 卷) |
| 英文标题 |
| Analysis on Train-Bridge Dynamic Simulation for Reinforcement of the 32 m Through Steel Plate Girders on Existing Line |
| 摘要 |
| 为配合沪宁线250 km·h-1 提速改造工程，运用车桥耦合振动方法，从车辆和桥梁动力响应角度，对一挠跨比、跨中梁体横向振幅及横向加速度均超过《铁路桥检规》通常值的32 m下承式钢板梁进行加固方案比选。车—桥仿真计算结果表明加强主梁可以明显提高桥梁的竖向刚度和横向刚度 |
