Scaled Model Tests on the Influence of Reinforcement Spacing on the Deformation of Reinforced Retaining Wall

Reinforced earth retaining wall is a kind of retaining wall which can bear lateral pressure of soil, which is made up of fill, stressed geosynthetics and retaining blocks. It can enhance the strength and stability of soil with the interaction between the reinforced material and the soil by arranging the tensile material, especially geogrid, in the tensile deformation region of the soil. In the researches on reinforced soil retaining wall, scaled model tests are more effective than any other methods Domestic and foreign scholars have done some valuable researches, but the reinforcement spacing effects of the retaining wall were still not fully resolved currently in academic sector. In this paper, different reinforcement spacing walls were made and monitored, and some research analysis have been done on the deformation characteristics of reinforced retaining wall with different reinforcement spacing. The results show that the settlement on the top as well as the lateral displacement on the front surface of the reinforced retaining wall increased with the increase of the reinforcement spacing.
