Abstract
It has been suggested by the results of actual construction that earth reinforcement methods have the binding effect other than the original effect that the methods supplement tensile strength to embankment structures. At the present stage, the mechanism and measure of the binding effect have not been clarified sufficiently. The limit equilibrium method is widely used for the design practice of earth reinforcement. It is not easy for the method to represent the binding effect, because the method cannot evaluate the stress distribution within reinforced embankment considering the deformation and stiffness of materials. This paper aims to definite the binding effect, by discussing the design technique of earth reinforcement considering the deformation and stiffness. The validity of the technique is verified by applying the technique to some field model tests.
