为了验证和完善桥上无缝道岔计算理论,进行桥上无缝道岔缩尺模型试验,用相似理论设计了有碴轨道道床纵向阻力试验模型,试验证明,采用同断面的混凝土枕时,道床纵向阻力偏大,采用木枕的轨道模型能够近似满足桥上无缝道岔道床纵向阻力的相似要求。
In order to verify and improve the calculation theory of seamless turnout on the bridge, the seamless scale test of seamless turnout on the bridge was carried out and the longitudinal resistance test model of ballast track railroad bed was designed by the similar theory. The test proves that when the concrete pillow with the same section is adopted, The resistance is too large. The track model with wooden pillow can meet the similar requirements of the longitudinal resistance of the seamless turnout on the bridge.
