| 摘 要： | 采用有限单元法，研究了双方孔板式无砟轨道结构的静力学特性。双方孔板式轨道作为一种新型的板式轨道结构，在纵向荷载、横向荷载和温度荷载作用下，随着轨道板长度的变化，各部件应力、变形值基本呈线性变化，但量值均较小，结构的力学性能优于日本板式无砟轨道。

| Abstract: | Static characteristic of double-pore slab ballastless track is studied with finite element method.For double-pore slab track,as a new type track structure,each component stress and deformation value basically assume linear change with the changes of track slab length under the effect of longitudinal load,lateral load and temperature load,but both quantity and value are smaller,and structural mechanics performance is superior than that of Japanese slab ballastless track. |
