| 摘 要： | 在综合我国预应力混凝土结构设计规范和无粘结预应力混凝土结构研究成果的基础上，考虑预应力钢筋的无粘结作用，提出了客运专线板式轨道轨道板的配筋设计检算方法；研究了预应力钢筋数量对轨道板裂缝宽度的影响，结果表明，对于设计速度较低或列车荷载较小的线路，轨道板的预应力钢筋可以适当减少。

| Abstract: | On the basis of combination of prestressed concrete structural design criterion and unbonded prestressed concrete structure research result,considering unbonded effect of prestressed reinforcing bars,this paper puts forward the verification method of track slab reinforcement design in passenger dedicated line and studies the influence of the number of prestressed reinforcing bars on track slab crack width.The result shows that for the railway line with slower design speed or lighter train load,the prestressed reinforcing bars for track slab can be properly reduced. |

| Keywords: | track slab unbonded prestressed reinforcing bar design verification crack width |
