Abstract

An analysis of covariance and Pearson correlation coefficient were performed to identify the relationship between both variables: traffic volume and crack. For this, it was carried out to analyse 216 tunnel inspection/diagnosis results with respect to the traffic. As a result, it has been proven that traffic volume and cracks in concrete linings are highly correlated. Therefore, it is recommended to consider traffic volume in planning of preemptive maintenance such as crack repair, etc.

본 연구에서는 교통량과 균열 두 변수에 대한 관계성을 분석하기 위하여 공분산 분석 및 피어슨 상관관계 분석을 수행하였다. 이를 위하여 국도터널 216개소에 대한 정밀안전점검, 정밀안전진단 시행결과 및 교통량을 조사/분석하였다. 분석결과 교통량과 콘크리트 라이닝에 발생하는 균열은 높은 상관성을 보이는 것으로 나타났다. 따라서 균열 보수 등 선제적 유지관리는 교통량을 고려한 계획수립을 수행하는 것이 바람직하다.
