the finite -difference procedure has been used to simulate the dynamic behaviour of a modular - block reinforced soil retaining wall height of 6m under seismic loading . To consider the effect of soil non-linear behavior a realistic non-linear soil model is incorporated into the finite difference code used in this study in this study the walls were constructed step by step and a transient uniform pressure was applied to each soil lift to take into account the compaction process.
