Micro-Macro Behaviour of Material in Soil Mechanics

摘要

In this paper model of partially saturated porous media is put forward. In particular, it considers the voids filled with water, vapour, gas, and air. The description of multiphase system at microlevel is today based either on the mixture of theory integrated by the concept of volume fractions, or on averaging theories and a classical viewpoint of Biot's theory which is involved in Desai's concept. The real behaviour of the aggregate is described by the concept of damage of Desai and eigenparameters help to involve other phenomena occurring in soil.
