The geogrid-reinforced earth retailing walls have been widely applied to geotechnical reinforcement constructions. A viscoelasto-plastic model is employed to consider the rheological properties of backfills and foundation soils while the empirical nonlinear viscoelastic model proposed by the authors is used to take the creep behaviour of geogrids into account. The numerical analysis procedure based on finite element method is developed for evaluation of stresses and deformations of geogrid-reinforced earth retaining walls under long-term loading. The comparative computations are conducted to examine the effects of construction process

geogrid length and spacing on long-term performance of geogrid-reinforced earth retaining walls. It is shown that the filling process have a considerable influence on the lateral displacements of panel

pullout forces and strains of geogrid and horizontal and vertical deformations of foundation The geogrid used for reinforcement will induce the redistribution of stresses in backfill. Both rheological effect of soils and creep effect of geogrid seem disappear after a certain period.
