Laboratory small scale tests to study the behavior of reinforced soil wall

A number of laboratory tests have been performed to observe the behavior of a steep reinforced soil wall in small scale model. In these tests the effect of the tensile strength of reinforcement layers and the effect of vertical interval spacing of reinforcement layers have been evaluated under the plane strain conditions. In computing the safety factor and interpreting the results, various values of the affecting parameters and different options of computing formulae have been examined for finding the best fitting quantities and to achieve the most reliable analytical interpretation. It was found that if the tensile strength of reinforcing elements and also the effect of side friction of the container are inserted into the modified Bishop's formula, then this formula reveals the most reliable analysis for the failure conditions. Because of the limited allowed pages, only very brief explanations can be presented in the present article.
