Abstract: In this paper, the prototype measurement for the tensions of the reinforcements, the earthfill settlements, the lateral earth pressures on the facing, the displacements of the facing and their changes under the train load of a retaining wall, which located at the Tianlin station,Guangxi province, on Nankun railway and reinforced by a new type of reinforcing bar and wedgy concrete block reinforcement, were described. The tension distribution law of the tied reinforcement and their changes with earth filling, and the change and distribution law and their influence factors of the lateral earth pressures on the facing, the horizontal displacements and the earthfill settlements were analyzed and studied.
