Abstract
Sand soil discharge, which seemed to be the liquefaction damage, was observed in the backfill of a quay wall structure during the Pohang earthquake in 2017. This discharge occurred because the bearing capacity decreased owing to the loss of effective stress, which was caused by the increase in the excess pore-water pressure with the dynamic loads from the earthquake. In this study, the effects of the variations in the N-value of the backfill of the quay structure and the seismic acceleration coefficient were investigated for increasing excess pore-water pressure and decreasing effective stress, owing to the dynamic load from earthquakes.
