港湾構造物のライフサイクル管理

抄録

Port authorities are interested in the behavior of the civil engineering elements of port infrastructure, particularly with respect to the financial, technical, safety and environmental decisions to be taken during the life-time of the structures. It therefore follows that to avoid unexpected large-scale rehabilitation measures as a consequence of neglected periodic maintenance, a systematical planning and budgeting of maintenance activities is necessary. Life Cycle Management (LCM), and its precursor Whole Life Costing (WLC), will contribute to a realistic approach of maintenance policy, including decision-making, planning, budgeting and funding of inspection and repair activities during the life-time of port structures.
PIANC PTC-II Working Group 31 (WG31) was constituted in 1993 to review and offer guidance on the use of LCM for new and existing structures in ports and published the LCM Report in 1998. In accordance with the LCM Report, the significance and outline of LCM, the outline and example of WLC and the case study of LCM are presented.
