路基地段CRTSⅢ型板式无砟轨道力学特性研究

Study on mechanical properties of the CRTSⅢ slab track on subgrade

通过建立路基地段CRTSⅢ型板式无砟轨道有限元模型,对轨道板、底座板受力响应随结构参数变化的规律进行了分析,得出的一些结论可为路基地段CRTSⅢ型板式无砟轨道结构设计提供参考。

By establishing the finite model of CRTS Ⅲ slab track on subgrade, the response to the track plate and the base plate along with change of structure parameters is analyzed, concludes some conclusion, so as to provide a reference on the design of CRTSⅢ slab track on subgrade.
