Abstract

The purpose of maintenance monitoring is to offer the objective and continuous data in order to be lasting security affirmation and best fitted maintenance of tunnel structure. Though recently the examples of maintenance monitoring which Is applied to tunnel are rapidly increasing, long-term measured monitoring actual results and rationally analysis method researches are wholly lacking. In this study, it is analyzed that the relationship of stress and reinforcement stress of concrete lining, i.e., last support materials of tunnel through regression analysis based on the monitoring result of the subway tunnel, which was accomplished the monitoring for long period, passing the weathering. Also, through the analysis of the stress and the safety of concrete lining, it is estimated that the frequency of maintenance monitoring and the in-situ application of the criteria value of management.

유지관리 계측은 터널 구조물의 지속적인 안전성 확인과 최적의 유지관리가 되도록 객관적이고 연속적인 자료제공을 목적으로 한다. 최근 들어 각종 터널에 적용하는 사례가 급속하게 증가되고 있으나, 현재까지 터널에서 장기간 측정된 계측실적도 적고, 합리적인 분석방법 연구도 전무한 실정이다. 본 연구에서는 장기간 계측이 수행된 지하철 풍화대 통과 터널의 계측결과를 회귀분석하여 터널의 최종 지보재인 콘크리트 라이닝의 응력과 철근응력의 상관관계를 파악하였다. 또한, 터널 콘크리트 라이닝의 응력과 안전성의 분석을 통하여 유지관리 계측 빈도 및 관리 기준치의 현장 적용성을 검토하였다.
