In the scope of this study, failure tests were performed in plane strain conditions with a model cantilever retaining wall supporting two different sands placed in layers so as to have same internal friction angle. The passive and active cases were created by moving forward and backward the model wall very slowly. Failure surfaces and geometry of active and passive wedges behind the wall were observed. As a result of model tests it was determined that in passive case shape of the wedge is similar with the other studies in the literature. However, observed failure surfaces and shape of active wedge was quite different from generally accepted Coulomb’s wedge theory. However, Coulomb’s wedge theory and Rankine’s theory can be applied to find active and passive earth pressure with suitable failure surface assumption of soil wedge.
