港湾施設の維持管理におけるLCM (ライフサイクルマネジメント) の考慮～桟橋の点検結果による対応策の試行的検討～

抄録

This paper attempts to incorporate life cycle management technique in the process to maintain the harbor facilities. Since deterioration will force the pace in many harbor facilities, it is necessary to implement optimal maintenance strategy. Taking steel pipe piles of pile-supported wharves for example, some of the piles need repair because of their severe circumstances against corrosion. It is important to minimize the expected cost during the extended lifespan of the structure to select an appropriate repair method. In this paper we predict the degree of corrosion on steel piles from the result of site inspection and estimate the expected cost to repair the predicted deteriorated area on the piles.
