A series of triaxial test were conducted to test three different reinforced methods and the strength characteristics of the reinforced loess with five different moisture contents respectively.The result indicated that the reinforcement could significantly reduce the influence of the moisture content on the strength of loess;the strength increased with the number of reinforcement layers and the strength of the ambient pressure when the moisture content kept the same,decreased with increase of the moisture content when the ambient pressure and number of the reinforcement kept the same,which demonstrated that the reinforcement loess was of water sensitive and the sensitivity became stronger with the number of the reinforcement layers. Within a certain moisture content limit,the strength index of Mohr-Coulomb decreased linearly with the increase of the moisture content and the internal friction angle reduced much more than the cohesion.Finally an equation was established to link the shear strength of the reinforcement loess and the moisture content,which were well matched.
