整体道床无缝轨道纵向温度力分布规律研究

Study on the Distribution of Longitudinal Temperature Stress along Welded Continuous Rail on the Solid Ballast

以整体道床上的新型轨道为基础 ,提出了一种用于计算此类轨道纵向温度力分布的新模型———轨道爬行。以此为计算依据 ,给出了计算温度力分布的公式和方法 ,指出了其一般性和在设计此类轨道时应注意的事项 。

In this paper, a new model based on a track on the solid ballast for analyzing the longitudinal temperature stress distribution of welded continuous track is presented. According to the new model, the formula and the method for analyzing the longitudinal temperature stress distribution are given, some attentions on designing the track are discussed, and the relation to the conventional model is also established.
