Abstract

Under the "Act on Safety Control of Small Public Facilities (enacted in 2015)", each local government selects and conducts annual safety inspections for small public facilities. Among small public facilities, small bridges pose high risks and are heavily utilized by local residents, making them challenging to manage due to their large numbers and limited resources. Therefore, there is a need for a rational selection method that considers the management capacity of local governments, as well as the establishment of objective risk evaluation and maintenance planning for small hazardous facilities. In this study, we propose a selection method based on structural and functional classification of small bridges, considering the management capacity of local governments. Additionally, we present quantitative evaluation indicators for ten risk evaluation criteria, aiming to facilitate objective risk evaluation.

「소규모 공공시설 안전관리 등에 관한 법률(2015 제정)」에 따라 각 지자체에서는 소규모 공공시설을 선정하고, 매년 안전점검을 실시하고 있다. 소규모 공공시설 중 소교량은 세천과 더불어 재해위험성이 높고 마을주민의 공공이용성이 높은 시설이나, 그 개소수가 매우 많아 지자체의 한정된 인원으로 관리하기 어려운 시설에 해당한다. 따라서 지자체의 관리능력을 고려하여 합리적인 선정방법이 필요하며, 객관적 위험도 평가를 통한 위험시설의 선정 및 정비계획의 수립이 요구된다. 이에 본 연구에서는 지자체의 관리능력을 고려하여 소교량의 구조적, 기능적 분류를 통한 선정방법을 제시하고, 위험도 평가 10개 항목의 정량적 평가지표를 제시함으로써 객관적인 위험도 평가가 이루어질 수 있는 방안을 제시하였다.
