本讲座概述了多孔介质理论在地质力学方面描述粒状材料的可能性，例如，饱和或不饱和土壤或粒状岩石等，在目前的调查中，多孔介质理论被称为经典的混合物理论扩展的体积分数的概念。这种方法，假设统计分布和叠加连续与内部相互作用，意味着不同的场函数的多孔固体基质和各自的孔内容物所表示的平均功能的宏观尺度。
This lecture outlines the possibilities of porous media theories in describing granular materials in geomechanical context as, for example, saturated or unsaturated soils or granular rocks, etc. In the present investigations, porous media theories are referred to as classical mixture theories extended by the concept of volume fractions. This approach, assuming statistically distributed and superimposed continua with internal interactions, implies the diverse field functions of both the porous solid matrix and the respective pore contents to be represented by average functions of the macroscale.
