| 摘 要： | 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。

| Abstract: | The surrounding area of convex block of single-pore track slab can be filled with resin or CA mortar.This paper separately establishes mockup of single-pore track slab under these two filling modes with finite element method.Comparative analysis is carried out on the stress of track structure under the effect of longitudinal load,lateral load and temperature gradient load.It is indicated that filling with resin is better than filling with CA mortar. |
