On the base of macroscopic and meso-scopic testing on cemented soil in the situation of saturated with water
a damage evolving variable is proposed corresponding with a meso-damage constitutive model established. Not only initial density of water but also initial damage of cemented soil has influence on damage evolving variable. Compared with experimental curves of cemented-soil
it is shown that the damage constitutive model has in good coincidence with the testing results. And the constitutive model can describe the damage characteristic of cemented soil saturated with water.
