Abstract：Research purposes:5-element Nishihara 's rheological model of cohesion soil and creep model of geosynthetics are used to study long term behaviors of reinforced cohesion soil retaining wall. Additionally, the interaction effects of reinforcement and fills, panel and fill and panel and panel are rationally considered. The layer- by-layer filling process of backfills of retaining wall is also simulated. Nonlinear computations based on 2-D FEM are numerically implemented by hybrid algorithm in which the incremental scheme is incorporated. Furthermore, Denver test wall of cohesion soil has been simulated by proposed method here.
Research conclusions: The simulated results agreed with the measured results well. Vertical displacement for top surface and lateral displacement for panel are affected by rheology of reinforced structure. Stresses of reinforcement increased with time at the beginning, during a specified time the stresses in it decreased and the reinforcement showed the behavior of relaxation.
