Geomaterials are a class of random heterogeneous materials that are endowed with a rich and complex microstructure involving various phases. As such, coupled transport and mechanical processes of great importance in many contemporary engineering problems can only be effectively analyzed using a micromechanical approach with multiscale modelling. Most current methods of analysis are largely phenomenological, requiring a large number of parameters that lack physical significance.

岩土材料是一类具有丰富而复杂的微观结构的随机非均质材料。因此，在许多当代工程问题中非常重要的耦合运输和机械过程只能有效地使用多尺度建模的微观力学方法进行分析。大多数当前的分析方法主要是唯象的，需要大量缺乏物理意义的参数。
