In this study, in order to verify the effects of damaged quantities to maintenance prioritization with performance evaluation system, crack conditions which were subdivided as per performance evaluation grade, critical maintenance part and priority part are considered as evaluation factors of prioritization. This result prove that maintenance prioritization has been changed by damaged quantities.

With the recent earthquake measuring 5.4 in Pohang, attention is being raised to the effects of the structures caused by the earthquake. In this study, seismic effect of the tunnel structure was analyzed by the time history analysis method using the measurement results of the nearby structures. Most of the analysis results showed displacement and stress results of one tenth level of the artificial seismic wave using design seismic acceleration, and the actual field survey revealed that the effects of earthquakes were minor.

Domestic facilities are managed in accordance with the "Special Law on the Safety and Maintenance of Facilities", and are managed through periodical inspection and safety diagnosis. In the inspection and diagnosis of such facilities, Comprehensive analysis results from exterior and non-destructive survey, and the five grade of the facility is managed. Most of the non-destructive tests are carried out in consideration of operation. In this paper, the purpose of this study is to investigate the change of compressive strength and the characteristics of the core strength in the ○○ tunnel.

Domestic social infrastructures have been rapidly growing based on economic growth in the 1970s. Recently, the construction of various methods has been continuously being carried out in accordance with the development of construction technology. Due to these influences, Maintenance work is becoming as important as construction.

This study is for the damage with lack of drain pipe length and it is presented for the improved references which is ｢Design and management guidelines of road drainage facilities｣.

성수대교･삼풍백화점 붕괴사고 등을 계기로 유지관리 분야의 중요성이 대두되면서 1995년 시설물의안전관리에관한특별법이 제정되어 점검･진단이 실시되는 등 본격적인 유지관리체제가 시작됐다. 그러나 점검･진단의 역사가 일천한 관계로 점검･진단에 대한 기술수준이 낮았고 연구 성과 또한 미흡하여 부실 점검･진단에 대한 우려가 상존해 있었다. 이에 2002년 평가제도가 도입 되면서 부실 점검･진단 비율이 지속적으로 낮아져 왔다. 그러나 최근 점검･진단 실시결과 평가실적에 따르면 향후 부실 점검･진단비율이 더 이상 낮아지기 힘든 경향을 보이고 있다. 이를 계기로 부실 점검･진단과 관련하여 관련기관의 설문조사와 메커니즘 측면에서 고찰하므로 서, 부실 점검･진단이 초래되는 근원적인 문제점을 나열하였고, 이를 바탕으로 현행 평가제도의 개선방향을 제시 하고자 하였다.

시설물의안전관리에관한특별법이 1995년 제정된 이후 정밀점검 및 정밀안전진단을 실시하여 국가의 주요시설물의 안전 확보에 기여해 왔다. 그러나 관리주체의 안전등급 판정 개입, 안전진단전문기관의 저가수주, 진단기술력 부족 등으로 점검․진단의 실효성에 관한 의문이 꾸준히 제기되어 왔다. 이에 평가제도가 도입되어 부실 점검․진단 방지로서 역할과 기능을 하고 있지만, 앞으로 부실 점검․진단비율을 더 이상 낮아지기 힘들다는 의견이 대두되고 있다. 따라서 현행 평가제도와 부실 점검․진단비율에 대한 현황 분석을 실시하고, 부실 점검․진단으로 인한 국가적 손실비용을 추정함으로서 현행 평가제도 개선의 필요성과 당위성을 제시하고자 하였다.
