Structure Design for Shear Cam of Vibration Damping CRTSⅠ Slab Track on Passenger Dedicated Line

针对减振型CRTSⅠ型板式无砟轨道的凸形挡台进行受力分析和计算,考虑了列车荷载的纵向力、横向力即温度力等对凸形挡台的受力影响,并分别推导出了这些荷载影响因素对凸形挡台受力的计算公式。最后对减振型板式轨道的凸形挡台进行受力计算和结构设计,给出了凸形挡台的结构配筋方式。

The paper makes mechanical analysis and calculation for vibration damping CRTSIslab track. Stressing influences such as the train longitudinal force and lateral force （that is temperature load） on shear cam are taken into account and calculation formulas of shear cam force caused by these factors are deduced. Finally the paper carries out stress analysis and reinforcement design for shear cam of vibration damping slab track, and presents reinforcement arrangement of shear cam.
