摘要
基于材料构成的多样性及路面所处环境的多变性,形成了柔性路面实验结果和由之得到的本构关系的分散性和多样性。通过分析多种理论和实验模型,进行了柔性路面本构空间研究。定义了柔性路面核子空间、检验空间、本构空间和路面范数。给出了最能反映该柔性路面所处环境下的物理过程本构关系的选择方法。可用这一本构关系所反映的物理规律进行路面设计和寿命估计。
Because of the dispersion of the pavement materials and the levity of the environment, the results of experiments for flexible pavement and the constitutive relation, which is summarized from the experiment results, have the character of dispersion and multiplicity. The constitutive space of flexible pavement is studied through the analysis of many theoretical and experimental models. And the nuclear space, test function space, constitutive space and pavement norm are defined. The best method to select constitutive relation according to the environment is introduced. The physics principle reflected by the constitutive relation can be used in pavement design and lifespan estimate.
