| 摘 要： | 基于桥上无缝线路线-桥-墩-基础一体化计算模型,利用ANSYS有限元优化技术研究了40 m+64 m+40 m客货共线铁路连续梁桥墩顶纵向水平线刚度的限值,以制动力作用下的梁、轨快速相对位移作为控制标准,得出该梁型墩顶每线纵向水平线刚度不宜小于1 000 kN/cm的结论。

| Abstract: | Based on continuous welded rail-pier-foundation integration model,the limit value of longitudinal linear rigidity of pier for 40 m+64 m+40 m continuous beam bridge on railway line for passenger and freight traffic is studied using ANSYS finite element optimization technology.With the standard of beam-rail fast relative displacement under braking force,it is concluded that the longitudinal linear rigidity of pier should not be less than 1 000 kN/cm. |

| Keywords: | beam-rail interaction continuous welded rail optimization design longitudinal linear rigidity of pier |
