Steel construction is one of the commonly used methods in building construction due to its efficiency in terms of time and cost. In particular, the top-down method using steel frames is widely used in the construction of underground structures in urban areas to shorten the construction period. However, there is currently no standardized cost estimation for subway steel frame construction in Korea, causing difficulties in determining the expected cost. In this study, we aim to provide basic data for establishing a cost estimation standard for subway steel frame construction through on-site surveys of subway steel frame construction commonly used in urban areas.

교통조건의 개선이 지역개발을 촉진시키는 주된 요인으로 알려져 있다. 본 연구는 도시 교외지역에서 지하철 건설에 따른 상업용도 건축물의 개발효과 측정을 목적으로 하고 있다. 이 목적을 위해, 대구 교외지역에서 지하철이 도입됨에 따라 지하철역과 노선주변에 얼마나 많은 상업용도 건축물이 개발 되었는가에 대해 지리정보시스템(GIS)을 이용하여 조사하였다. 분석한 결과는 첫째, 상업용도 건축물은 지하철의 개통연도에 맞추어 개발되는 경향이 강하게 나타났고, 둘째, 상업용도 건축물의 개발효과는 노선전면이 노선이면보다 크며, 토지이용도 노선전면의 밀도가 높았으며, 셋째, 역 구간별 입지적 특성에 따라 건축물의 개발특성은 달리 나타났다.

Urban subways usually make environmental problems because subway vibrations are transmitted to building structures. However, when the buildings are designed, vibrations due to subway are not usually considered in advance. This results in many environmental vibration problems after buildings are constructed. This study was carried out to set up and evaluate a pre-assessment technique for the environmental impact of urban subway vibration on newly planned buildings near a subway line. for this purpose, semi-emperical method was set up and vibration measurements were made on site in accordance with construction schedule. Computer simulation was also performed using ANSYS software to predict the building vibration and compared with the measured results for evaluation of the pre-assessment technique.

The purpose of this study is to propose and verify a spatial network construction method that integrated roads and subway lines to improve the predictability of the urban spatial analysis model. The existing axial map for urban spatial analysis did not reflect the subway line that serves as an important moving space in modern cities. To improve this axial map, proposed a Ground-Underground Spatial Network by integrating the underground spatial network with the axial map. As a result of the integration analysis, the Ground-Underground Spatial Network(GUSN) were similar to the movement frequency. Correlation of GUSN was 0.723, which showed higher explanatory power than correlation coefficient of 0.575 in axial map. The result of this study is expected to be a theoretical basis for constructing spatial network in urban space analysis with subway.

According to the current eligibility criteria in Korea, only cities with populations of more than one million are eligible to carry out urban rail transit construction projects. This paper suggests measures for improving such systems by reviewing current eligibility criteria for the construction of urban rail transit including subway and LRT in Korea.

The subway station is not only an effective means to solve urban traffic problems, but also a kind of representative city shelters with a variety of functions such as urban beauty and disaster prevention. At the same time, the subway station as public facilities need activate the urban functions and through the effective design schemes for a variety of the facade of underground entrance to improve users' awareness and reliability for the subway station as a city shelters. This study is conducted to purpose the design direction considering design and disaster preventing characteristics of the underground subway station entrance. In addition, it will provide a basic reference for the subway station in the renovation and construction. The study is composed of literature reviews and field survey. The literature reviews through papers and documents related to the city shelters, the components and characteristics of city shelters, and components and characteristics of facade design of underground entrance at subway station. Before the field survey through the online surveys with evacuation capabilities and screening only the subway station. And field survey is conducted on the site with careful observation and confirmation. Last cluster analysis were applied to the finally selected samples by the SPSS Win18.0

도심지에서의 교통인프라 개발이 활발해 지고, 대심도 지하터널을 이용한 도시의 기반시설 확충으로 인하여 기존 운영되거나 설치된 시설물 또는 구조물 상호 간의 근접시공이 많이 이루어지고 있다. 이에 따라 근접시공으로 인한 시설물 또는 구조물에 미치는 안정성 확보여부는 중요한 이슈가 되고 있으며, 관련법에 의하여 지하터널공사에 따른 지하안전영향 평가를 반드시 수행하여야 한다. 본 연구에서는 근접시공으로 인한 정거장구조물 의 거동특성을 파악하기 위해 동북선도시철도 터널이 계획된 노선 상부의 지하철 6호선 고려대역 정거장 구조물을 대상으로 신설터널에 의한 기존 구조물에 미치는 안전영향평가를 수행하였다. 이를 위하여 정거장구조물의 안전영역 평가 및 굴착방법에 대한 검토와 3차원 수치해석을 통한 상세검토를 수행하였다. 구조물 손상도 평가, 궤도 틀림 및 기존 구조물과 건물 안정성 평가 결과 근접터널공사에 따른 기존 정거장 구조물의 안정성은 확보되는 것으로 평가되었다. 본 연구는 도심지 터널공사에서 근접시 공시 기존의 인접구조물에 미치는 영향을 사전에 검토하는 경우 기본적인 기초 참고 자료로 활용될 수 있을 것으로 기대된다.

This paper studies on the benefit evaluation of urban railway construction project. We compares Korean Method with Japanese in calculating the generalized cost(GC) of a trip. In Japan, the disadvantage of transferring to another mode or line is included to calculate GC of trip. And environmental effects are contained directly as rail construction benefit. But in Korea, inconvenience of transferring facilities like stairways and passageway for riding a subway is not accounted to analyse benefit. As a result, there is a little investigate to improve and overcoming the inconvenience facilities of transfer, access, and egress. So, we suggest the containing the disadvantage measure of transferring facilities when subway riderships are forecasted. That will be reduced tile capital size of subway.

It is impossible to precat the behavior of ground soil and structure accurately during underground construction in urban area or excavation in soft ground area because of difference between the assumed design condition and the actual site condition. Therefore, it must be managed by measuring system and correct the difference by real data. Large scale under ground construction in urban area like a seoul subway project has needed for Intelligent Construction technique, a field of the Engineering Contractor. The automated measuring system is developed for the technique. It is described that the procedure and the method of measuring work with application of the automated measuring system.
