In the current evaluation method of seismic performance for the road bridge abutments, the effect of earth pressure from the liquefied layer has not been taken into consideration yet. Therefore, to rationally evaluate the seismic performance and retrofitting effect of the existing abutments, it is necessary to consider the earth pressure due to soil liquefaction.In part 3, the verification simulation for the model tests was performed using the proposed model of the earth pressure. It was confirmed that the calculated results were consistent with that of the experimental results.
