Model Experimental Research of Double-Sided Reinforced Earth Retaining Wall

Abstract

Double reinforced earth retaining wall belongs to flexible structures, so it adapts well to soft foundation deformation. Compared with other forms of retaining wall, double reinforced earth retaining wall is more economic. An experimental study was conducted to assess the earth pressure on the facing of double-sided reinforced earth retaining wall, and its fundamental mechanism was researched. The results indicate that the horizontal earth pressure on the back grows with the increase of the thickness of the filled soil, its value was between active earth pressure and static earth pressure, the strain of the metallic bar increases with increasing load, It was non-linear distribution along the length of the metallic bar. The results providing a basis for design, theoretic analysis and engineering application.
