Shaking table tests are conducted to investigate the effect of vertical seismic motion on the response of caisson type quaywall-ground system. Both eartbquake wave and sine wave are used as input wave. Earthquake-wave test indicates that the larger the amplitude of vertical seismic motion is, the hrger the permanent displacement of the caison is, that is, vertical seismic motion is a dangerous factor for caisson type quaywall-ground system. Sine-wave tests suggests that the phase diffierence between vertical and horizontal seismic motion has some effect on the behavior of the system. ƒL�[ƒ��[ƒh�i‰p�j�F - ‹LŽ–‹æ•ª�F - ‹æ•ª �@�@�@ˆÏˆõ‰ï˜_•¶�W
