摘　　要：通过文克尔弹性地基梁模型,建立梁的挠曲微分方程;引入无限长梁及半无限长梁的边界条件进行求解。以昌九城际轨道交通乐化梁厂存梁移梁滑道为例,分析了不同工况下滑道的受力情况,确定了滑道受力最不利的工况。Based on the model of Winkler elastic foundation beam, established deflection differential equation for the girder,mean- while the boundary conditions are introduced to solve the equation. As an example, the track which used in storage and transfer girder of Nanchang-Jiujiang intercity rail transit Lehua girder prefabrication yard are calculated, various force situation for the track in different condition are analyzed. The worst force situation are determined.
