Taking sand as the research object in the village of Tuanjie,Kunming city,a series of triaxial tests are carried out on unsaturated soil and after treated by ionic soil stabilizer. After treated by ionic soil stabilizer,the mechanical strength deformation characteristics and stress strain relation curve of unsaturated soils are compared under different water content and confining pressure. For without adding ionic soil stabilizer and ionic soil stabilizer of unsaturated sand to analysis the deformation modulus,fitting stress-strain relationship to normalized equation study,the change rule of Duncan-Chang model parameters of unsaturated sandy soil is obtained,which provides reference for the theoretical study of modified unsaturated sandy soil.
