摘要
针对隧道内合成轨枕无砟轨道结构形式,应用有限元分析Ansys软件,建立钢轨-扣件-合成轨枕-橡胶层-道床板-弹性基础的有限元分析模型,分析不同合成轨枕下橡胶层刚度、合成轨枕参数对合成轨枕无砟轨道结构的影响,为大瑞线无砟轨道结构的设计和施工提供依据。
According to structural form of ballastless track of composite sleeper in tunnel,finite element analysis model of steel rail,fastener,composite sleeper,rubber layer,track bed and elastic foundation is established using finite element Ansys software to analyze the influence of different rubber layer rigidity and composite sleeper parameters on ballastless track structure of composite sleeper,which provides basis for design and construction of ballastless track structure of Dali-Ruili Line.
