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。
The finite element method is used to solve the stability problem of the small radius curve. The maximum radial displacement and the maximum radial force of the small radius CWR at the highest temperature are calculated. Taking a practical project of a work section as an example, Specific reinforcement measures for small radius curves (R = 300 m) on subgrade, bridge and tunnel.
