夏季高温天气持续，很容易造成轨道结构内部温度过高，导致轨道结构变形失稳。为了得到夏季高温条件下 CRTSⅡ型板式无砟轨道结构内部的温度分布传递特性，根据京沪高铁津沪线路所桥上CRTSⅡ型板式无砟轨道结构特点，以实测轨道表面的温度变化曲线为边界条件，建立了 CRTSⅡ型板式无砟轨道三维实体模型，得到温度在无砟轨道内部的分布和传递的一般规律。结果表明本文所建模型能够准确、有效地用于无砟轨道内部温度特性研究。

Summer continuous high temperature weather easily causes the high internal temperature of rail structure and leads to deformation instability of track structure. In order to get the internal temperature transfer characteristics of CRTSⅡ slab-type ballastless track in summer high temperature condition and according to CRTSⅡ slab-type ballastless track structure characteristics of JinHu block station bridge in Beijing-Shanghai high speed railway, CRTSⅡ slab-type ballastless track three-dimensional entity model was established and general distribution and transfer law of ballastless track internal temperature was concluded by taking temperature variation curve of measured track surface as boundary conditions. T he results showed that the model presented in this paper could be used to internal temperature characteristic study of ballastless track accurately and effectively.
