The purpose of this study was to investigate the installation interval space and its effect of the back supporting beams in Assembled Earth Retaining Wall(=AER-wall). A comprehensive experimental and analytical study has been conducted.
In this test, a prototype model of AER-wall was made and tested. Major variables include the installation interval space of the back supporting beams and the slope of the retaining wall. From this test, it is found that the structural stability is improved compared to the other retaining wall structures, by adding the back supporting beams. The resisting ability of this wall on the soil pressure is improved. The observed soil pressure tested in this retaining wall reduced about 17 percent compared to the calculated soil pressure. It is found that the optimal area ratio of the back supporting beams is 0.2, considering the rotation of retaining wall and soil pressure according to the area ratio of back supporting beam. A three dimensional numerical analysis is conducted in this study. From this analysis, it is found that the installation of the back supporting beams is very efficient, especially in the case of the difficulty in sufficient base length of retaining wall structure.
