Abstract

 In this study, the authors focus on sheet-pile structures in port facilities, and propose maintenance/rehabilitation policies of sheet piles and a methodology for determining the priority of maintenance/rehabilitation of them, in order to reduce expected lifecycle costs under budgetary restrictions. In detail, the authors formulate a mechanical model for evaluating the structural stability of sheet-pile against seismic force and propose a hybrid simulation model for determining the priority of sheet pile maintenance/rehabilitation based on the evaluation results of structural stability and designing desirable maintenance/repair policies and prioritizing rules so as to reduce estimated lifecycle costs considering seismic risk as much as possible under budgetary restrictions. In addition, the effectiveness of the proposed methodology is discussed through an case study targeting actual sheet piles in a port facility
