无轨枕整体道床厚度研究

The study on the depth of no-sleeper monolithic roadbed

结合上海市轨道交通某工程的工程难点,采用解析法和有限元单元法,对特殊条件下无轨枕整体道床的厚度及道床的整体内力、整体剪应力和螺栓孔周边混凝土应力分布进行了验算,为研究无轨枕整体道床厚度提供了理论依据。

Combining with the engineering difficulties of rail transit some engineering in Shanghai, the depth of no-sleeper monolithic roadbed under special condition was calculated using analytical method and finite element unit method from whole internal force of ballast, whole shear stress and bolt hole fixed edge concrete stress distribution, so as to provide theoretical basis for studying no-sleeper monolithic roadbed depth.
