Recently, the damage which is caused by human misfortune in the underground space have increased. However the regulation and law for the underground space safety is still poor. Therefore in this paper, we propose the scheme for the construction of safety management systems on underground multiplex facilities. We analyze the problem of the current law, and present the scheme for the underground shop fire fighting facility. It contains the tree structure to management the underground space according to the construction phase, the facility and immediacy equipment. This safety management system will rearrange the scattered underground space management system.

Open-cut method has been widely used to construct underground structures, but it causes several problems such as traffic congestion and public resentment resulting from severe construction noise and ground settlement. In many cases, it is very difficult to build underground structures safely due to the unknown locations of buried facilities such as water pipes, drainage pipes, gas pipes and high-pressure cable conduits etc. Also in open-cut method, moving buried facilities causes additional cost and extension of construction period. Therefore, this paper is to present a case study in which Tubular Roof construction Method (T.R.c.M.), a newly developed construction method for underground structures using slab steel pipes and PC wall trench, is applied for the construction of a subway tunnel in Seoul. As a result, it is found that T.R.c.M. is a construction method by which tunnels can be constructed safely without any effect on the surrounding environment and traffic flow due to the minimized construction vibration and noise.

Nowaday, local governments have planned to manage intelligent underground facilities through the u-City project. But, the intelligent underground facilities are in need of the progressive approach because of the required huge financial resources. Therefore, the objectives of this research are (1) to prioritize the monitoring items of sensing technology developments, (2) to study technological feasibilities, and (3) to discover the killer application which expands ripple effects on economy. To achieve these objectives, final monitoring items were derived from the business analysis of the water supply, the local government survey, the hearing expert opinions and so on. The priority order of final monitoring items were technology developments of (1) the flowmeter flux, (2) the water leakage/crack, (3) the pressure of water supply pipes, and (4) the flux of filtration plants. The research significance is obtained from the derivation and the evaluation of the priority order and the actual demand for the water supply facility management. And, the research results will contribute to the strategic planning for the underground facility intelligence.

Now, there are some problems to manage underground facilities in domestic. Specially, in the case of KEPCO(Korea Electric Power Corporation), it is so difficult to manage electronic line more stably and detailedly because the geographic information and attribute information being built is not easy to be updated in the field. KEPCO officials who are accompanying management and supervision in earthwork do not have sufficient knowledge and information about GIS but they grasp the information of geography and property which coincide with the field. Therefore they have to refer their business analysis contents sufficiently for more efficient lines management in the KEPCO, but it is problem that the existing information of electronic lines management system is not. In this study, we constructed power transmission and power distribution underground facility management system for the user to manage and maintain underground facilities more easily and safely using the information of geography and property about power transmission and power distribution underground facility which have been built by KEPCO.

Most of public underground facilities are installed under the ground, thus it is difficult to recognize the accurate location even with the drawings. Studies are conducted to understand exact position of underground facilities using augmented reality. However, in those studies, establishing of additional 3D object model database is needed when AR system is used at field. Because most of public underground facility information are established as 2 dimensional. In this study, AR system is developed as mobile application which can use original 2D underground facility data to transfer 3D AR data automatically without additional 3D database establishment.

Underground environmental infrastructure and energy production facilities, which are recognized as avoidable facilities such as landfills, are emerging as an important social issue due to urbanization and economic growth. It is necessary to analyze the stability according to various ground conditions and load conditions for the construction of large-scale underground complex plants. In this paper, horizontal/vertical displacement and stress distribution according to the load condition and construction process were analyzed using finite element analysis (FEM), Based on the analysis results of various conditions, factors to be considered in the detailed design and construction of the underground complex plant were reviewed and the implications on design factors (Intermediate wall installation status, Pre-reinforcing area, etc.) for underground large space construction were derived.

In this study, the shared facilities and space in the multi-family housing which residents could maintain contacts with their neighbors were investigated and analyzed. It could find the shared facilities and space so that residents could maintain to contact with their neighbors after surveying the dwellers requirements. Also it could specify the importance of the neighborhood common spaces and the conditions for the planning of the shared facilities. Analyzing residents requirement of set-up location, this study lead to the following suggestions concerning the facilities design: In the first neighborhood-circle, it require to be related the household affairs of housewives on the adjacent space to a dwelling-unit. In the second neighborhood-circle, it require especially the facilities for children play, study, reading, hobby etc. These facilities need establish each 4-5 floor in high-rise building estates. The roof & underground floors has been recognized in important & essential place for living facilities. Therefore, it is needed to improve to get ready to receive the various facilities.

This study investigated the characteristics of architectural planning in the youth training centers, which were introduced to the magazines from 2000 to 2010. The result are as followings. Firstly, the youth training centers were located mainly in general residential area, that the youth could be easily accessible. And, it were located mainly in green natural area, which is adjacent to the mountain or park. The site area of the youth training center was analyzed to approximately $10,000m^2$ below. Secondly, the placement and the form of the youth training center is divided two types, which are a single and two buildings type. A single building case is found the type of 'ㄴ' and 'ㄷ' shape, and two buildings case is found the type of 'ㄴ + ㅡ', 'opened ㅁ', 'ㅡ + ㅡ' shape. It is found mostly the type of 'ㄷ' shape. Thirdly, the youth training center is planned mostly with fifth stories above ground and three underground levels. And, sometimes it is planned a mixed-use buildings with a sports center, community center and senior welfare center. Lastly, the space of youth training center is zoned horizontally for each mass of building, which is planned the educational, cultural and sports facilities. And, it is zoned vertically some of the sports facilities and administrative support facilities in the underground, and a educational and cultural facilities on the ground.

Due to recent extreme weather, the information of the reliability for the nation's major social overhead capital (SOC) is emerging as a major issue. So the real-time monitoring of the underground state has become a very important. This paper is about a open USN platform for the underground information collection. Various sensors to collect information for the underground is used. The interface and the power of each sensor may vary. In order to solve the interface and power problem, this paper refer to the open interface, the network required for an open platform and the energy problem.
