摘要

在许多城市，有轨电车运行几个月后，轨道旁的沥青在交通荷载作用下经常出现裂缝。主要原因是钢轨柔性材料的强度不足以为沥青提供支撑。钢轨柔性材料的强度与其结构密切相关。本文通过选取壁厚、肋板间距等参数来改变钢轨柔性材料的结构。通过建立有限元模型，计算不同结构在交通荷载作用下的变形。最后提出了钢轨柔性材料的合理结构参数。

Structure Design of Rail Flexible Material Based on Mechanical Calculation

In many cities, the asphalt beside the rail at intersection often cracks under traffic load after tramcar running for several months. The main reason is that the rail flexible material is not strength enough to provide brace for asphalt. The strength of rail flexible material is closely related to its structure. In this article, several parameters such as wall thickness, interval distance of ribbed slabs and so on are chosen to change the structure of the rail flexible material. The deformations under traffic loads of different structures are calculated through building finite element models. At last, reasonable structure parameters of the rail flexible material are recommended.
