Abstract

According to the Facility Management System (FMS) operated by the Korea Authority of Land & Infrastructure Safety, it is expected that the number of aging facilities that have been in use for more than 30 years will increase rapidly to 13.9% in 2019 and 34.5% in 2929, and end up with a social problem. In addition, with the revision of "Common Application of Seismic Design Criteria" by the Ministry of Public Administration and Security in 2017, it is mandatory to re-evaluate all existing road facilities and if necessary seismic reinforcement should be done to minimize the magnitude of earthquake damage and perform normal road functions. The seismic performance management-decision support technology currently used in seismic performance management practice in Korea only determines the earthquake-resistance reinforcement priority based on the qualitative index value for the seismic performance of individual facilities. However with this practice, normal traffic functions cannot be guaranteed. A new seismic performance management decision support technology that can provide various judgment data required for decision making is needed to overcome these shortcomings and better perform seismic performance management from a road network perspective.

현재 국내에서 내진성능관리 실무에 사용되고 있는 내진성능관리-의사결정 지원기술은 개별시설물의 내진성능을 정성적인 지수 값에 근거한 내진보강 우선순위만을 결정하고 있어 내진보강이 되었음에도 불구하고 지진 시 도로가 정상적인 교통통행기능을 수행하지 못하는 상황이 발생하고 있다. 이러한 단점을 극복하고 도로망관점에서 내진성능관리를 수행할 수 있도록 의사결정에 필요한 다양한 판단자료를 제공할 수 있는 새로운 내진성능관리 의사결정지원 기술이 필요하다. 본 논문에서는 교량, 터널, 사면, 옹벽으로 구성된 포항시 도로망을 대상으로 "지진위험도평가"를 적용하여 정량적인 지진 전·후 직·간접 피해규모 산출, 내진보강 전후의 직·간접 피해규모 비교에 의한 내진보강효과 검토, 이를 통해 수행 할 수 있는 내진보강 우선순위 선정, 필요예산 계획, 방재도로선정 등의 다양한 의사결정 사항들을 제시하였다. 또한 지진 위험도평가 방법을 이용한 내진성능평가를 시각적으로 구현하여 의사결정자들이 직관적으로 의사결정을 수행할 수 있도록 지원하기위해 개발된 의사결정지원 소프트웨어를 소개하였다.
