摘要
用有限元分析方法求解小半径曲线的稳定性问题,计算出在最高轨温状态下小半径无缝线路的最大径向位移以及最大径向力,以某工务段的实际工程为例,提出了在路基、桥梁和隧道小半径曲线(R=300 m)线路中的具体加固措施。
For the stability calculation of the continuous welded rails with small radius curve under maximal track temperature, this paper calculates the biggest displacement and radial force by means of the finite element method. For the reinforcement design of the continuous welded rails with small radius curves(R = 300 m), the reinforcement measures of the roadbed, bridge and tunnel are proposed.
