| 摘 要： | 本文主要针对轨排-道床结构中存在的流变力学现象,应用流变力学的基本理论与研究方法,探讨轨道结构的力学问题。通过实验研究和系统理论分析,揭示轨排-道床结构的弹性、塑性和粘性等流变力学特性,建立了轨排-道床结构本构关系模型。并与原苏联所建立的轨排-道床结构流变模型进行了对比,说明了所建模型的合理性、正确性。通过此项研究,为进一步探讨铁路轨道结构的力学问题、完善高速铁路轨道结构的设计及养护维修工作打下良好的基础。

| Abstract: | This paper is mainly concerned with the rheologic phenomena in the structure of track plane and ballast of railway. Based on the rheologic theory, the problems of track mechanics are studied. After a systematic experimental research, the rheologic mechanics characteristics of the ballast, such as its elasticity, plasticity and stickiness, are revealed and a theoretical model is developed for it. In comparison with that of former USSR, it is shown that the present model is more reasonable. The present work lays down the foundation for further study of the mechanical properties of track structures and improvement of design methodology and maintenance for high-speed railway. |
