Abstract: The analysis of reinforced soil is regarded as two stages: viscoelastic stage and visco-elastoplastic stage. The creep performance of geosynthetics is considered. Elastic strain of reinforced soil, stress of geosynthetics and horizontal microstress of soil in viscoelastic stage are given. Stress relaxation appears weakening by negative index as the time increasing. At the same time strain of geosynthetics is increasing. The time and deformation corresponding to initiation of the plastic stage are given. Stress in the reinforcement remains constant in visco-elastoplastic stage. But the deformation remains increasing due to creep. Therefore the stress and strain in reinforced soil can be analyzed in different cases history. Then severe consequence due of strength and stability weakening and deformation increasing, can be reduced.

Key words: creep, reinforced soil, geosynthetics
