| 内容記述 | It is necessary to identify infrastructures relatively deteriorating fast, and to monitor, repair and renew the infrastructures. However, regarding methods to extract the infrastructures from inspection data obtained through ordinary inspections, there is actually no systematized methodology. In this paper, the authors propose the multi-stage mixed Markov deterioration hazard model and its multi-hierarchical Bayesian estimation. Furthermore, the benchmarking analysis towards stratified deterioration speeds corresponding to decision making levels and the methodology to extract intensively monitored infrastructures on each level are proposed. In order to verify the effectiveness of the proposed methodology, empirical analysis is carried out using the visual inspection data of 10,689 expansion joints in 21 lines of actual highway. The authors first mentioned that the deterioration process significantly depends on (1) kind of expansion joint, (2) kind of surface layer pavement and (3) traffic volume, and clarified that the expected life span of the expansion joints is about 18 years and it varies about 5 years due to the above mentioned factors. Then, it was found that the expected life span of the expansion joints varies from about 9 years to about 55 years by considering the heterogeneity of each line. Furthermore, the authors clarified that the expect life span varies from about 5 years to more than 100 years in the fastest deteriorating line by considering the heterogeneity of each expansion joint. Finally, by using the estimated result, the authors carried out the relative evaluation of hazard rate and extract the intensively monitored expansion joints. |
