土木構造物の維持管理と劣化進行のハザード形状

抄録

This paper formulates the survival quantile model for analyzing the increasing hazard shape of a structural deterioration progress. The Gompertz model is specified in order to express the type of late-coming hazard of structural deterioration, and also the log-logistic model is specified to draw the type of peak hazard of deterioration. These models are applied to the bridge component and the pavement road surface and the paper shows the estimated results. The author mentions the maintenance policy implication for the irregular hazard shape of structural deterioration processes, for instance an index of time for peak point, structural monitoring scheme, maintenance scenario for an irregular hazard shape.
