보행 현수교의 수명 예측 및 AADS 기반 스마트 통합 안전관리 프레임워크 구축

초록

Following the rapid nationwide construction of pedestrian suspension bridges, the Ministry of Land, Infrastructure, and Transport (MOLIT) and the Anti-Corruption and Civil Rights Commission (ACRC) proactively established routine inspection manuals and safety guidelines in 2024. Although these governmental efforts have significantly raised safety awareness, their reliance on visual inspections and local municipal budgets presents structural limitations in practical applications. This study aims to constructively advance these guidelines by proposing an integrated proactive safety management framework based on engineering data and automated technologies. First, a lifespan prediction model using the Palmgren-Miner rule considering combined loads was established, and the institutionalization of mandatory non-destructive testing (NDT) such as magnetic flux leakage (MFL) was proposed. Second, highlighting the economic feasibility of proactive safety investments through quantitative cost comparisons based on life cycle cost (LCC) analysis, this study proposed a 3-tier governance model and a special disaster prevention fund (ring-fencing). Third, an active access denial system (AADS) equipped with noise-filtering algorithms and linked with national disaster APIs was introduced to automate the disaster response. This study offers a practical smart standard model that technologically and institutionally completes the current administrative guidelines, providing significant academic and policy implications for national disaster prevention.
