| 高速鐵路橋上無縫線路縱向附加力研究(27 卷) |
| 英文標題 |
| Study on the Additional Longitudinal Forces Transmission between-Continuously Welded Rails and High-Speed Railway Bridges |
| 摘要 |
| 采用實體單元模擬橋梁及橋梁墩臺、空間梁單元模擬鋼軌、彈簧單元模擬橋梁與墩臺及軌道之間的連接, 建立梁—軌縱向相互作用三維有限元空間力學模型。以豐沙線永定河單線鐵路橋梁、秦沈線沙河雙線鐵路橋梁對其進行計算驗證。以秦沈客運專線32 m多跨雙線整孔簡支箱型梁橋為例進 |
