The effect of sheet piling on both uplift and RC shear deterioration related to cracking of concrete and yield of steel is focused as a possible way of damage control of existing infrastructure. The uplift of underground structures is expected to be fairly confined by sheet piling of higher cost performance as investigated in the past researches. Concurrently, the amplified shear damage to RC ducts is newly found as a trade-off. But, its increased damage of RC ducts is estimated to be acceptable in view of urban infra-stock management in practice.}, publisher = {Society for Social Management Systems}, title = {Proposed Damage Control of Underground Infrastructure by Sheet Pile Construction at Liquefiable Urban Areas}, volume = {6}, year = {2010} }
