摘要
针对铁路散体道床在轨道平面中存在的流变力学特性 ,通过系统地实验研究和理论分析 ,揭示道床的弹、粘、塑性等流变力学性质 ,建立合理的道床流变理论模型的本构关系 。
This paper is mainly aimed to study the rheologic mechanics characteristics existing in the track plane of the railway crushed stone ballast. Through the systematic experimental research and the theoretical analysis, the rheologic mechanics characteristics of the ballast, such as elasticity, plasticity and stickiness, are revealed and a reasonable theoretical model has been built for it. This study sets a sound foundation for further research on the deformation property of the continuously welded rail (CWR) track under the train's loads.
