The Shear Behavior of Composite Material for Retaining Wall

In these days, the composite material is popular as a material of Retaining wall because of the advantages of economy and construction. In general, retaining wall is not estimated for the stability of structure, but some of retaining walls that are composed of composite materials became thin because of the highly dense materials. So the concern of shear failure for the structure is rising. Because standard test criterion and large scale tests equipment are rarely available, few studies are performed. So, in this study, we performed large scale direct shear tests for various confining stresses(147, 294, 441 kPa), and estimate shear behavior of composite material by the relation of shear stress - displacement and vertical - shear displacement.
