Study on the Limit of Longitudinal Linear Rigidity of Pier for Continuous Beam Bridge on Railway Line for Passenger and Freight Traffic
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40m+64m+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.
Based on continuous welded rail-pier-foundation integration model, the limit value of longitudinal linear rigidity of pier for 40m+64m+40m 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.
