Abstract Triaxial compression tests of reinforced saline soil with wheat straw and lime，reinforced uniformly at upper，lower and whole positions，were carried out to research the effect of reinforced position on stress-strain and shear strength characteristics. Moreover，strength model of reinforced saline soil with wheat straw and lime was discussed by WU model theory. The results show as follows：(1) Shear strength and anti-deformation capacity of lime soil in three reinforced positions are improved. (2) Reinforced position is related to the increase in cohesion，but has little effect on the internal friction angle. (3) Shear strength of reinforced saline soil with reinforcement in lower position is larger than that in whole and upper positions；and the reinforcement of lower position is helpful to the reinforcement function. (4) Strength model of reinforced soil with wheat straw shows that strength of reinforced soil is closely related to the distribution pattern of wheat straw. The research results are of important guidance for understanding the reinforcement mechanism of reinforced soil with natural fiber material.
