道床横向阻力及轨道不平顺对无缝线路稳定性影响定量分析

Quantitative Analysis of the Extent of Influence of Roadbed Lateral Resistance and Track Primary Curvature on the Stability of CWR

利用无缝线路稳定性理论，从计算入手，定量分析了道床横向阻力和轨道原始不平顺对无缝线路稳定的影响程度。并结合轨道的实际工作状况，提出了提高临界温度力值的具体措施。

Using the stability theory of continuous welded rail tracks,this paper quantitatively analyses the extent of influence of roadbed lateral resistance and track primary curvature on the stability of tracks. Combined with the practical operation in roadbed tracks,a concrete method for improving the stability of tracks is presented.
