摘　　要：文章采用有限元分析的方法,建立了无缝道岔温度力与位移的有限元力学模型。基于文章建立的有限元模型,对无缝道岔在实际工程中常见的4种工况进行分析计算,研究结果为无缝道岔的设计、养护维修提供了参考价值。A finite element model of displacement of the jointless switch with temperature stress is established by FEM; the four working conditions of the jointless switch that are commonly seen in operation are analytically computed based on this model. The study made in this article is of referential value to the design and maintenance of joindess switch.
