单孔轨道板凸台周边填充层有树脂填充和CA砂浆填充两种方式。文中运用有限单元法分别建立两种填充方式下的单孔轨道板实体模型,对轨道板分别施加纵向、横向和温度梯度三种荷载,对比分析轨道结构的受力情况,结果表明,用树脂填充优于用CA砂浆填充。
Perforated track plate bosses filled with resin filling and CA mortar filling in two ways. In this paper, the finite element method is used to establish the solid model of the single-hole track slab with two kinds of filling methods respectively. Three kinds of loads of longitudinal, transverse and temperature gradient are respectively applied to the rail slabs. The stress distribution of the rail structure is contrasted and analyzed. Better than filling with CA mortar.
