 note = {The present paper deals with an effect of vertical seismic motion on soil liquefaction. A new DEM program was proposed for this study by considering an effect of vertical motions in the equation of motion. Detailed approaches of calculating the volume change of pores and excessive pore water pressure were given. The results of simulation indicated that the excess pore water pressure could rise in case of only vertical shaking. The numerical simulation made it possible to explain microscopically an effect of vertical motion on soil liquefaction. The results in this study agreed to those of the shaking table tests done by the authors., 金沢大学理工研究域地球社会基盤学系},
