정부에서는 안전사고의 방지, 기존시설의 수명연장과 성능개선을 통한 재정투자의 효율성을 제고를 위하여 「지속가능한 기반시설 관리 기본법(이하 “기반시설관리법”, 공포 ’18.12.)」을 시행(’20.1.)할 예정이다. 이 법에서는 개별법에 따라 상이하게 관리되는 기반시설의 유지관리 수준을 상향 평준화하기 위하여 최소유지관리 공통기준을 제정하도록 하고 있으며, 기반시설 관리체계의 분석과 정부시책에 대한 검토 등을 통하여 유지관리 개선 방향을 결정하고, 이를 근거로 최소유지관리 공통기준을 마련중이다. 공통기준의 지침화를 위해 기반시설 유형별 적용성을 평가하여 범용성과 확장성을 검토할 예정이다.

시화호조력발전소는 시화호 수질개선과 전력생산을 위한 목적으로 건설된 세계 최대 발전용량의 조력발전소이다. 조력발전소 운영으로 시화호 수질은 비약적으로 개선되었지만, 해양환경적인 변화가 나타났다. 해양환경 모니터링을 위해 K-water 시화조력관리단은 2014년부터 해양관측시설을 설치하여 현재 16개소를 운영 중에 있고 생태계의 건강성, 다양성, 생산성 등 구조변화를 파악하기 위해 해양관측자료를 수집 중에 있다. 이렇게 생산된 해양관측자료는 기후변화에 따른 정책 수립, 관계기관의 시화호 활용계획 등으로 활용되고 더 나아가 다양한 수준의 요구가 존재하게 되었다. 사회적 요구에 부합하기 위해서는 해양관측시설에 대한 철저한 관리와 함께 관측자료 품질을 파악하고 선별하는 관측자료 고도화의 중요성이 부각되고 있다. 특히 지역적인 특성상 해양에서 운영되기 때문에 다양한 문제가 발생할 수 있어 정상운영을 위해서는 예방적 유지관리 활동이 필수적이다. 현재 국내·외에서 해양관측시설을 운용하는 기관은 다양한 사용자의 요구를 만족시키기 위해 고품질 자료관리 시스템 개발, 국제적인 관측 표준화, 품질관리 표준화, 유지관리 기준 등을 수립하고 관리되고 있다. 하지만 시화조력관리단에서 운영 중인 해양관측시설은 법제화된 관리기준과 관측장비 운영방법이 정립되지 않아 효율적인 유지관리가 어려웠다. 이에 본 연구는 국내에서 운영 중인 해양관측시설의 유지관리 활동과 법제화된 규정을 분석하고, 기관별 공통요소를 도출하여 시화호조력발전소에서 운영 중인 해양관측시설의 독자적인 법규를 제정하였고 합당한 유지관리 기준을 수립하였다. The Sihwa Lake Tidal Power Plant is the world's largest tidal power plant with the purpose of improving the water quality of Sihwa Lake and generating electricity. The operation of the tidal power plant has improved the water quality of Lake Sihwa by leaps and bounds, but changes in the marine environment have occurred. To monitor the marine environment, K-water's Sihwa Tidal Power Management Team has been installing marine observation facilities since 2014 and is currently operating 16 sites, collecting marine observation data to identify structural changes in ecosystem health, diversity, and productivity. The ocean observation data produced is used to establish policies for climate change and to plan the utilization of Sihwa Lake by related organizations, and furthermore, various levels of needs exist. In order to meet social needs, the importance of upgrading observation data to identify and select the quality of observation data along with thorough management of ocean observation facilities is emerging. In particular, since they are operated in the ocean due to their regional characteristics, various problems may occur, and preventive maintenance activities are essential for normal operation. Currently, institutions operating ocean observation facilities at home and abroad are establishing and managing high-quality data management systems, international observation standardization, quality control standardization, and maintenance standards to satisfy the needs of various users. However, the marine observation facility operated by the Sihwa Tidal Power Administration has been difficult to maintain efficiently due to the lack of legislated management standards and observation equipment operation methods. Therefore, this study analyzed the maintenance activities and legislated regulations of the marine observation facilities operated in Korea, derived common factors for each institution, and established independent legislation and reasonable maintenance standards for the marine observation facility operated by the Sihwa Lake Tidal Power Plant.

This Study was investigated in main breakage types of 50 interlocking block pavements in apartment houses and evaluated on their performance. According to performance evaluation, maintenance control index of 9 aged interlocking block pavements ranged 7.9 to 8.9. These values meant that the condition of interlocking block pavements were still good. Therefore, it was concluded that the 10-year cycle of the block replacement recommended by Ministry of Construction & Transportation is necessary to reappraise. To objectively evaluate the performance of interlocking block pavements, this study presented the criteria of maintenance control by combining two maintenance control standards suggested by Ministry of Construction & Transportation and the Japan Interlocking Block Pavement Engineering Association. Also, this study suggested that the domestic standard is necessary to include durability standards and quality standards of joint filling materials and bedding sand layer for increasing expectation life and reducing maintenance costs of interlocking block pavements

제3궤조 전차선 급전레일은 주위온도와 전류로 인하여 발생하는 열 때문에 길이 방향으로 신축변화하며, 그로 인한 각각의 급전레일들 사이에 기계적, 전기적 문제가 발생하지 않도록 하기 위하여 길이 변화를 수용할 수 있는 신축장치(Expansion Joint)를 사용한다.최근 신설되는 경량전철은 제3궤조 전차선 급전방식을 주로 적용하고 있으나, 급전레일온도에 따른 관리 및 유지보수기준이 명확하게 제시되지 않고 있다. 또한, 영업운전으로 인한 급전레일 급전중에는 신축장치의 상태변화를 확인할 수 있는 시스템이 구축되어 있지 않으므로, 검측을 통하여 측정된 데이터를 분석하여 최악의 환경에서도 장비성능을 유지하며 운용되는지 검증할 필요가 있다. 본 논문에서는 제3궤조 전차선의 운용경험을 토대로 급전레일의 온도변화에 따른 신축변화를 조사·분석하였다. 그 일련의 과정들을 통해 신축장치의 신축량 조사·분석 방법과 분석결과에 따른 신축장치의 유지보수기준 적용 방법을 제시하고자 한다. The third rail of conductor rail occur the rail expansion and contraction to length direction by surrounding temperature and electric current produced heat. In order to avoid both mechanical and electronic problem between each of the conductor rail, expansion joint normally is used to accommodate the change of the length. Lately, the newly created light rail transit is mainly applied the third rail of conductor rail with method of electric supply, the standards which include management and maintenance according to temperature change of conductor rail is not presented clearly yet. Besides, during the supply of power that conductor rail by business driving, the system which Inspect variable of expansion joint is not constructed. Therefore, it should be examining status of expansion joint even in the worst of circumstances maintaining and working capabilities instruments through analyzing measurements data. In this thesis examined and analyzed the rail expansion and contraction based on the management experience about the third rail of conductor rail. We kindly suggest the method of investigation and analysis that amount of expansion about expansion joint. And also, the standard application method of administration and maintenance of expansion joint in accordance with analytical researches through a series of those process as well.

The railway platform is an important facility closely related to the safety of passengers, trains, and images of railway facilities, and requires thorough facility management. However, the problem that the finishing material (plastering mortar) for the joint finishing of dissimilar materials (concrete+granite) falls off in the direction of the track at the platform podium is occurring multiple times across the country. Since these problems threaten the safety of train operation and the safety of passengers, immediate and continuous management is required. This study tried to derive improvement plans through the analysis of the drop-off problem of finishing materials occurring at the platform podium. The status of missing finishing materials for the platform podiums of about 200 railway stations and the related design and construction standards of the Korea National Railway were investigated. After that, the cause of the drop-off of the finishing material was analyzed, and as a result, it was found that the main cause was the boundary between the roadbed and the architectural process that occurred during construction. Subsequently, in connection with the derived causes and design, construction standards, (1) improvement of finishing materials or construction methods, (2) design of finishing materials that are easy to adjust height, (3) design of separate finishing methods, (4) improvement methods and durability were suggested.

Pruning is the most important work for the growth and aesthetics of street trees. It is also the most actively conducted maintenance work. However, the specifications, application methods, and cost criteria for pruning have not been systematically established. This has recently caused a lot of confusion in the practice of street tree pruning, such as indiscriminate pruning and lack of construction costs. Therefore, this study clarified the contents of work according to the form of pruning. It added 'aesthetic pruning,' which takes into account design. In addition, It revised equipment not in conformity with the law and excluded personnel necessary for on-site traffic control so that they could be reflected separately. As a result, this study is expected to contribute a lot to securing appropriate construction costs for maintaining street trees.
