Abstract

This paper presents the results of an analysis of the discrimination accuracy of a bridge load carrying capacity estimation model based on data from inspection reports. The load carrying rate estimation model was derived using statistical methods through the collection of 2,161 inspection reports. By entering the bridge specifications and maintenance information, you can check the estimated load carrying capacity of the bridge. In order to verify the discrimination accuracy of the estimated load carrying rate model, the estimated load carrying rate was compared with the load carrying rate in the inspection and diagnosis report for 164 public bridges for which data was available. Although there are differences depending on the bridge type, the results were obtained with an accuracy of over 80% in determining the estimated load carrying capacity.

본 논문은 점검진단 보고서의 데이터에 기반한 교량의 내하율 추정 모델의 판별 정확도 분석 결과를 보여준다. 내하율 추정 모델은 2,161건의 점검진단 보고서 수집을 통해, 통계적 방법에 의해 도출하였다. 교량의 제원 및 유지관리 정보를 입력하면 해당 교량의 추정된 내하율을 확인할 수 있다. 추정 내하율 모델의 판별 정확도를 검증하기 위하여, 데이터 확보가 되어 있는 공용중 교량 164개소에 대해 추정 내하율과 점검진단 보고서 상의 내하율을 비교하였다. 교량 형식별로 차이가 있지만 추정 내하율 판별 정확도 80% 이상의 결과를 도출하였다.
