Abstract

When managing the infrastructure maintenance plan, it is desirable to consider countermeasures to minimize the damage even if an emergency event occurs and to recover to standard maintenance level promptly. However, the resilience perspective is hardly included in the planned maintenance repair plan. In this study, based on the idea of disaster resilience, consider countermeasures that can reduce damage (D) and measures that can shorten the recovery time (T). First, we explain points to be noticed at the respective stages before disaster occurrence, immediately after disaster, after disaster based on the four resilience characteristics (robustness, redundancy, resourcefulness, rapidity). Some countermeasures are proposed for improving resilience for each of the four resilience characteristics. Then, we evaluate how much damage can be suppressed compared with normal situation by resilience countermeasures. Also evaluate the degree of reduction in recovery time and evaluate the improvement effect of resilience capacity for three local governments.
