| 摘 要： | 为确定高速铁路单孔轨道板长度与凸台长度之间的合理比例,文中运用有限单元法建立单孔轨道板的实体模型,对轨道板分别施加纵向、横向和温度梯度三种荷载,对比分析各种不同比例关系下轨道板结构的受力情况,进而确定一个合理比值。结果表明,轨道板长度与凸台长度的比例保持在0.55～0.60为最好。

| Abstract: | In order to determine the rational proportion between single-pore track slab length and convex block length in high-speed railway,this paper establishes full-scale model of single-pore track slab using finite element method.Through applying longitudinal load,lateral load and temperature gradient on track slab,the stress of track slab under different ratios is compared and analyzed and thus a reasonable ratio is determined.It is shown that keeping track slab length and convex block length at 0.55 ～ 0.60 is the best. |
