摘要

Sea-side ground improvement is one of the techniques to increase seismic stability which will not interrupt the port-side activities during its execution. Centrifuge model shaking tests were conducted to investigate the dynamic response of sheet pile quay wall set on a thick clay deposit. An area at the sea-side adjacent to the quay wall was improved with cement-treated clay. Under 50 g centrifugal acceleration, the clay deposit was consolidated and four stages of shaking were applied to the quay wall. The recorded input-output accelerations, deflection of the quay wall, earth pressures along depth and pore pressures were used to evaluate the behavior of the stabilized sheet pile quay wall. The results of the study indicated that an improved area provides significant resistance against seismic load.
