Abstract The triaxial creep tests considering different confining pressures and geotextile reinforced layers were conducted using the large scale triaxial creep apparatus developed in-house. The creep properties and reinforcement mechanism under different deviatoric stresses and reinforced layers were obtained. The proposed PH model for reinforced soil described the relationship among stress，strain and time and the parameters of the PH model under different influence factors were obtained. Finally，the coefficient of reinforcement effect was established to evaluate the impact of stiffness under different reinforced layers. The results showed that the reinforcement effect was improved linearly as the increase of the reinforced layers. In comparing with the increasing compaction degree of the high fill，the reinforced materials reduce the post-construction deformation more effectively.
