Test and analysis of two-step retaining wall reinforced by geogrid

In this paper,the prototype measurement for the lateral soil pressures on the facing,the vertical soil pressures and the deformations of the geogrid on the two step retaining wall reinforced by the geogrid on Meikan railway, were described.The variation and distribution of the lateral and vertical soil pressures and the deformations of the geogrid with soil filling and time were analyzed,the cracked face of the wall was discussed.
