The cement mixing ratio was respectively selected as 5%, 10%, 15%, 20%, and the curing age was re-spectively selected as 7, 14, 21, 28 d to put forth the uniaxial compression test.The value of unconfined compressive strength and the change law of stress-strain curve for cement soil was obtained.Finally, the influence of cement mixing ratio and small age on mechanical behavior of cement soil were quantitatively analyzed, and the mathematical expression of stress-strain relation curve was granted, which could provide science foundation for applying cement soil into irriga-tion channel liner impervious engineering and civil construction engineering in the middle area of Inner Mongolian Au-tonomous Region.
