| Summary | Published in April 2004 IOT SERIAL No. 93-47-785, 68pp. Damage evidence of port structures under past earthquakes indicated that seismic stability was closely associated with liquefaction potential of the backfill. In this paper, the stability of existing anchored bulkheads under two types of backfill soil condition: the one with partially liquefiable soil, and the one without liquefaction potential, have been studied under peak ground acceleration of 0.1g of earthquake excitation. Parameters such as the embedded length, the maximum bending moments of the sheet pile walls, the maximum anchors pull, and distance of the anchor have been estimated. The results indicated that the structure is able to withstand the design earthquake without liquefiable backfill. However, if liquefaction of the backfill is an issue, seismic capacity of the structure, particularly the anchor, is insufficient. This result indicated that most of the damage of the steel sheet pile quay walls was caused by the failure of the anchor. |
