通过分析沥青混合料加载时的“固结效应”和卸载时的“永久变形”等流变学特征 ,提出了一个较为实用的流变学模型 ,并给出了模型参数的确定方法 ,该模型参数数目可多可少 ,且能满足Blotzmann叠加原理 ,可应用于应力随时间变化以及其它各种复杂应力状态的情况 .
By analyzing the “consolidation effect” during loading and the “permanent deformation” during unloading, a more practical rheological model is proposed and the method for determining the model parameters is given. The model The number of parameters can be more and less, and can meet the Blotzmann superposition principle, which can be applied to stress changes with time and other complex stress conditions.
