| 高速铁路桥上无缝线路纵向附加力研究(27 卷) |
| 英文标题 |
| Study on the Additional Longitudinal Forces Transmission between-Continuously Welded Rails and High-Speed Railway Bridges |
| 摘要 |
| 采用实体单元模拟桥梁及桥梁墩台、空间梁单元模拟钢轨、弹簧单元模拟桥梁与墩台及轨道之间的连接, 建立梁—轨纵向相互作用三维有限元空间力学模型。以丰沙线永定河单线铁路桥梁、秦沈线沙河双线铁路桥梁对其进行计算验证。以秦沈客运专线32 m多跨双线整孔简支箱型梁桥为例进 |
