the deformation and strength of loess are affected by water and load together
so the research of loess mechanics must take account of water and load effect together. In this paper based on the theory of thermodynamics and continuum damage mechanics and the energy conversion of loess in load and moistening
the damage variable
load damage and moistening damage of loess and their relations are put forward. The basic framework of the elasto-plastic damage models of loess which are made up of plastic
load damage and moistening damage are also put forward. This is a new method to put forward the structure model of loess.
