摘要
本文提出了分析无缝道岔温度力和变形分布的三节点力学模型和解题的二次松弛法（ＴｗｉｃｅＲｅｌａｘａｔｉｏｎＭｅｔｈｏｄ）。分析结果与国内外的实践经验一致。文章最后指出了结构上应注意加强的薄弱环节。
This paper presents a three-joint model and a Twice Relaxation Method for analyzing the distribution of rail temperature force and deformation of welded switches. The calculated results are in good correspondence with the practical experience both at home andabroad. The weak points which should be strengthened are also pointed out.
