【Abstract】 It is supposed that stress axial and material axial be matched and kept unchanged during the loading process.On the base,the author deduced the damage mode of cement-stabilized soil(CSS) and proposed evolutionary equation of damage of the CSS.The material parameters concerned of CSS were determined from the condition of unconfined axial compression under loading-unloading experiments.Through the comparison with the experimental results,the damage mode of CSS established by the author was proved reasonable.更多还原
