The velocity field method was applied to stability analysis of the earth reinforcement. The effect of the reinforcing material in soils was considered by the internal dissipation energy in the velocity field method. The additional shear resistance of the reinforcing material mobilized at the slip surfaces was evaluated as a direct link between the reinforcement force and the increase of the confining pressure due to pull-outforce. The internal dissipation energy of the reinforcing material was considered using the direct reinforcement material force. The active earth pressure in wall-reinforced soil was calculated through use of the idea of this paper.
