To improve the theoretical research on the tensile properties of soil, the damage model study was carried out in the present paper based on existing experimental results. In combination with the variation of the micro-structure of clay during the stretching process, the damage variable is defined by coupling the porosity with the pore distribution. According to the structure damage during the tensile process of clay under different initial conditions, the damage evolution equation is obtained and the damage model is established. At the same time, the applicability of the damage evolution equation and the damage model was verified by experimental data.
