Abstract:The triaxial consolidation drainage creep test of fiber reinforced loess is carried out. Through the different control of initial moisture content, reinforcement rate and confining pressure, the creep characteristics of reinforced loess are analyzed, and the following conclusions are obtained: adding basalt fiber into loess can effectively improve the creep of loess samples, and the restraining effect of creep deformation has no obvious monotonous relationship with reinforcement rate, there is an optimal reinforcement ratio; with the increase of water content, the creep deformation of reinforced soil increases, the reinforcement effect decreases, and the larger the partial stress is, the more obvious the phenomenon is; with the increase of confining pressure, the creep deformation of reinforced loess decreases, the reinforcement effect increases, and the larger the partial stress is, the more obvious the phenomenon is; based on the Mesri creep model, the test curve is simulated, and the parameters of the model are calculated. The triaxial creep characteristics of fiber reinforced loess can be fitted by Mesri model.
