Abstract
This paper discusses active earth pressure acting on concrete block retaining wall considering deformation and stiffness of wall and backfill material. Many laboratory model tests are performed, subjected to block retaining walls which have reinforced or unreinforced backfill, and which have different inclination. Earth pressure distribution and active thrust, etc. are monitored according to the displacement of retaining wall. The monitored results are simulated fairly well by proposed FE analysis which employs Mohr-Coulomb yield criterion, a simple non-associated flow rule, and initial stress method for nonlinear analysis. By applying the proposed procedure to the result of full-scale model test, it is shown that the procedure duplicates fairly well the results observed in the test.
