Description :
Based on the data of the electron scanning of loess microstructure and the soil tests, the paper presents a hypothesis : the collapsing deformation of loess comes from the damage of the microstructure stability. In accordance with this, a constitutive relation for collapsible loess is developed by means of micromechanics and damage theory, where the collapsing model of the microstructure is set up by the mathematical theory of catastrophe.
