【Abstract】 An expemental study of reinforeed earth with geosynthetics shows that it has strain-sofleing behavior. Based on this be-havior, a total stress-strain model with 3 stages (elastic nonlinear, plastic strain sofening and plastic flow) in accordancewith its engineering properties was proposed. The elastic-plastic constitutive equation is derived in plane strain and 3-dimen-sion situation respectively. An analysis of reinforeed earth retaining walls with geosynthetics by finite element with this modlhas been carried out, whose result is in good agreement with those of the model tests. The proposed calculating model can beused in the design of reinforced earth structure with geosynthetics.更多还原
