지하철 노선망 체계의 완성으로 서울시 도시교통난 완화를 위한 제3기 지하철9호선(김포공항~방이동) 901공구 현장(대우건설 이섬범 현장소장)을 찾았다. 서울시 지하철9호선 901공구는 서울시 강서구 개화동에서 김포공항 계류장 지하를 관통하는 3,285.5m 구간으로 901 현장은 농경지에 건설되는 차량기지 398,851㎡(약120,000평)와 김포공항 계류장 지하를 관통하는 구간이 있기에 어느 공구보다 안전 및 환경관리를 절대적으로 중요한 요소로 삼아야 하는 구간이다.

In this paper, field measurements in the subway tunnel and adjacent building were performed to predict the pound vibration level induced by urban rapid transit (subway) in Seoul, Korea. From the results of the measurements, the measured ground vibration level induced by subway in Seoul is smaller than the empirical formula of New York, but it is bigger than the empirical formula of Tokyo which has been commonly used in Korea. We suggested the empirical formula for prediction of ground vibration level induced by subway in Seoul considering on the wave propagation path for soils or rocks, respectively.

Steel has been widely used as a material in temporary structures. Corrosion attack often reduces the long-term durability of temporary steel members that are not protected from corrosion. In designing temporary steel structures, it is difficult to evaluate their long-term durability, since the thickness loss of steel members is not clear. In this study, laboratory and field exposure corrosion tests were performed on structural steel plate specimens, and the loss of thickness of specimens that were exposed to a subway construction site for 11 months and of specimens that were exposed to environments with controlled humidity and calcium chloride for six months were measured. Finally, a thickness loss equation was formulated based on the environmental conditions and the testing periods.

Recently, the utilization of subway stations for varied working spaces is beginning to receive more attention. However, due to feeling of closeness and rejection to the underground, a daylighting is useful to alleviate the complaints of subway environments. This paper aims to investigate and evaluate the luminous environments of subway stations with and without daylighting in Seoul. At the first stages, the field experiments are performed to estimate the illuminance levels of chosen three subway stations. And then, the interview and questionnaire surveys are conducted to evaluate the luminous atmospheres of them. As results, the daylighting effects to subway visual environments are analyzed. Also, the basic data for a daylighting design are suggested.

This study proposed cost prediction equation model by considering duration, construction, size, actual cost with the subway construction started by the actual cost system which was introduced since 2004. Costs - scale exponent n(confidence range: 0.5 to 0.7) for cost prediction of subway construction was drawn total cost(0.713), net cost(0.77) in point of the 11 subway construction data. The cost prediction equation model of the subway construction which was presented in this study is able to effectively apply to business planning, preliminary investigation, feasibility study, basic design stage to estimate the approximate cost in the future.

The metro played a role in improving and alleviating the problems of urban ground transportation, promoting rational development of the city and at the same time leading the development of metro-related industries. There is no doubt that it had a double effect of enormous economic and social benefits on the development of the country as a whole. The purpose of this study is to apply the concept of servicescape to the metro and establish the definition of the Metro Servicescape(MSS). To this end, the service space and service facilities of the metro were analyzed, and the existing domestic and foreign literature related to servicescape was studied. First, this study defined the concept of servicescape of metro. Second, 10 elements suitable for the metro service landscape were derived through domestic and foreign service landscape studies. Third, through field surveys and analysis of metros in five cities in Seoul, Busan, Daegu, Daejeon, and Gwangju, the ranking of the current status of the domestic metro servicescapes was 203 Seoul metro, 197 Busan metro, 192 Daegu metro, 178 Gwangju metro, There were 172 metro lines in Daejeon. Among them, the four elements of comfort, sociality, cleanliness, and safety are the same, and accordingly, it seems that each city metro is the same standard. However, the six elements of aesthetics, spatiality, convenience, entertainment, openness and information were found to be different for each city metro. It is expected that the results of this study can provide a reference value for future metro service landscape research.
