Abstract

In Korea, safety inspections of bridges are conducted periodically in accordance with law. Bridges are classified according to type, length, etdc., and the content and frequency of safety inspections are different. Bridges safety evaluation is performed on relatively large bridges, and safety evaluation of small bridges, which account for the majority of all bridges, is not mandatory. Therefore, in this study, in order to confirm the safety of small-scale bridges, a correlation analysis study was conducted with the common load carrying rate for each safety evaluation indicator. For this purpose, inspection reports of bridges from local goverments were collected, and the values for each bridges for about 50 indicators in the report were converted into data. By performing cleaning on the collected data and analyzing the correlation with the common load carrying rate, the top indicators related to safety for each bridges type were derived.

우리나라는 법에 따라 주기적으로 교량의 안전점검을 수행하고 있다. 교량은 형식, 연장 등에 따라 구분하고 안전점검 내용 및 주기가 다르다. 교량의 안전성 평가는 상대적으로 큰 규모의 교량에 수행하고 있으며, 전체 교량 중 다수를 차지하는 소규모 교량의 안전성 평가는 의무화되어 있지 않다. 따라서 본 연구에서는 소규모 교량의 안전성을 확인하기 위하여, 안전성 평가 지표별 공용내하율과의 상관관계 분석 연구를 수행하였다. 이를 위해, 전국 지자체 교량의 점검진단 보고서를 수집하였으며, 보고서 상의 약 50가지 지표에 대한 교량별 값을 데이터화하였다. 수집 데이터에 대한 클리닝을 수행하고, 공용내하율과의 상관관계 분석을 통해, 교량 형식별로 안전성과 연관있는 상위 지표를 도출하였다.
