In this paper a concrete block artificial bedrock as a wave impending barrier WIB is proposed to reduce the acceleration response of buried pipeline when applied underneath of trench . Its computational work for various thicknesses as numerical simulation is performed by employing 2-D finite element FE analysis , the soil un-drained FE mohr-coulomb model was defined as semi-infinite medium by using absorbent boundaries.
