  • 지하공간의 개발이 활발해짐에 따라 최근에는 지하와 관련된 안전사고가 자주발생하고 있다. 이와 관련하여 국토교통부에서는 『지하안전관리에 관한 특별법』(2018.01.01. 시행, 이하 지하안전법)을 시행하고 있다. 지하안전법의 핵심이 되는 내용 중에는 현재 우리나라에서 지하공간에 존재하는 지하시설물, 지하구조물, 지반의 지하정보를 3차원으로 가시화 할 수 있도록 지하공간통합지도를 구축하고 이를 활용하는 것을 포함하고 있다. 본 연구는 지하공간통합지도 중 3차원의 지하구조물 데이터를 대상으로 3차원 모델 생성 후 이를 빠르게 검수할 수 있는 프로그램을 개발하는 것을 목적으로 한다. 이를 위하여 우선 3차원 지하구조물 데이터를 생성하고 자동 검수하는 기술에 대하여 국내·외 현황을 조사하였다. 핵심이 되는 연구내용으로는 지하공간통합지도를 구축할 때 3차원 지하구조물의 검수기준에 따라 자동으로 3차원 모델 품질을 검수하는 프로그램을 개발하였다. 본 연구를 통하여 현재 수작업 방식으로 진행하고 있는 3차원 모델 검수과정을 98% 이상 자동화함으로써 지하공간통합지도 지하구조물의 3차원 모델의 품질향상을 도모할 수 있을 것으로 기대된다.

  • Recently, underground spaces can be usually applied to the alternative of land use for parking. However, lack of window and natural light are among the most cited drawbacks associated with dark image of underground. If underground parking lots are designed to be positive and safe environment for people, openings for daylighting will play a significant role. The natural light and unobstructed view to outdoor are main elements to create optimal underground parking lots. This paper focuses on investigating the actual day lighting conditions and evaluating the day lighting performance of openings as potential lighting resources. For the study, the field measurements and Questionnaire surveys are conducted. And then, the day lighting performance of underground parking lots based on opening geometry and orientation are evaluated by scaled model experiments. As results, the feelings of safety and orientation of underground parking lots are improved by openings for day lighting regardless of the sizes. The required illuminances (daylight factor 0.5%) for underground parking lots can be satisfied in the skylight opening ratio of 4% or more.

  • The urban land is incapacitated to grow and correspond to demand the space in urban area. And recently, rapid increasing of population and complex of urban function on pushed to develop the underground space. In Korea, the underground space development in inefficient in aspect. because development of underground space have not consistent and systematic planning method in underground environment inclounding interion design, extererior design. Therefore this study is suggested the design element for comfortable underground living environment and assortment on utilization of underground space. The results of this study on utilization are security of space through land use efficiency, conservation of historical place, building and natural environment, and technological characteristics, mental image. Accordingly, this study is proposed design element that make comfortable underground space as aspect from stimulation and diversity, sapciousness and feeling of warmth and dryness to compensate improper image of underground space, spacial orientation and way finding.

  • In recent decades, underground usage in urban areas has expanded from subways and utilities to include virtually every non-residential building function. Greater usage of underground space is envisioned in the more congested urban areas in the world such as Asia and Europe. This increasing interest in underground development is raising basic questions about whether people can work and live underground, and if so, what design techniques can sucessfully be employed. The actual experience of people in underground space, as well as general associations and image of the underground reveal predominantly negative attitudes. A number of design techniques have been suggested by researchers, or actually utilized by designers, to alleviate these potential problems for people in underground space. This paper identifies these psychological and physiological problems. In addition, design objective and possible solutions are briefly summarized. This is followed by a summary of special design problems and objectives related to road tunnels.

  • The underground space of urban entertainment center can do various roles for urban development. Especially, the design of underground space using natural elements is necessary to sustainable development of facilities. The purpose of this study is to propose the elements, characteristics and application around interior environmental design using natural elements in underground space of urban entertainment center. The research methods of this study are research references, survey and field-study. This study can be concluded as follows; First, the factors of interior environmental design using natural elements in underground space of urban entertainment center are 'landmarks expression of natural elements', 'introduction and planning of daylighting', 'planning of materials using natural images', 'planning of ecological footpath' and 'planning of energy recycling'. Second, pedestrian space and openspace considering regional context are necessary. Third, introduction of daylight and design of artificial lighting in underground space are needed to making eco-friendly environment. Fourth, landmark design using various natural elements in underground space is needed to provide eco-friendly amenity. Fifth, the interior environmental design using natural elements is needed to community space in underground space. Sixth, eco-friendly pedestrian space in underground space is necessary. Seventh, interior environmental design using natural elements is needed to the entrance of underground space of urban entertainment center.

  • Purpose: The underground air is the warm air discharged from the porous volcano bedrock 30-50m underground in Jeju, including excessive humidity. The temperature of the underground air is $15-20^{\circ}C$ throughout the year. In Jeju, the underground air was used for heating greenhouses by supplying into greenhouses directly. This heating method by supplying the underground air into greenhouses directly had several problems. The study was conducted to develop the heat pump system using underground air as heat source for resolving excessive humidity problem of the underground air, adopting the underground air as a farm supporting project by Ministry of Agriculture, Food and Rural Affairs(MAFRA) and saving heating cost for agricultural facilities. Method: 35kW scale(10 RT) heat pump system using underground air installed in a greenhouse of area $330m^2$ in Jeju-Special Self-Governing Province Agricultural Research & Extension Services, Seogwipo-si, Jeju. The inlet and outlet water temperature of the condenser, the evaporator and the thermal storage tank and the underground air temperature and the air temperature in the greenhouse were measured by T type thermocouples. The data were collected and saved in a data logger(MV200, Yokogawa, Japan). Flow rates of water flowing in the condenser, the evaporator and the thermal storage tank were measured by an ultrasonic flow meter(PT868, Panametrics, Norway). The total electric power that consumed by the system was measured by a wattmeter(CW240, Yokogawa, Japan). Heating COP, rejection heat of condenser, extraction heat of evaporator and heating cost were analyzed. Result: The underground air in Jeju was adopted as a farm supporting project by Ministry of Agriculture, Food and Rural Affairs(MAFRA) in 2010. From 2011, the heat pump systems using underground air as a heat source were installed in 12 farms(16.3ha) in Jeju.

  • 우리나라는 99,274 $km^2$의 협소한 면적에 산지가 약 70%을 차지하고 있다. 게다가 인구밀도는 세계 3위의 조밀한 국가이다. 따라서 우리나라는 지하공간을 새로이 활용해야 할 국토로 간주하고 적극적으로 개발할 필요가 있다. 우리에게는 지하공간개발이 선택이 아니라 필수이다. 국내에서는 1970년 이후로 가스 원유비축기지, 지하 양수발전소가 건설되었고 주로 대도시에서 지하철, 상가, 보도, 공동구, 주차장 등의 형태로 지하공간이 활용되어 왔다. 여수 지하석유 비축기지와 지하철은 세계적인 규모이다. 최근에는 지하공간의 개발이 더욱 다양화 되고 또한 대규모화 되고 있는 추세이다. 국내 지하공간 개발현황과 문제점 및 대책에 대하여 소개하였다.

  • 본 논문에서는 지하공간 통합지도를 탐사 현장에서 활용하기 위한 모바일 단말기용 서비스 시스템을 설계 구현한다. 모바일 단말기용 현장활용 서비스 시스템은 지하공간 통합지도 관리 시스템에서 제공하는 타일맵, 3차원 지형정보, 지하구조물, 지하시설물, 지반정보 등을 현재 위치에 따라 3차원으로 가시화하도록 설계되었고, 현장 탐사로 얻어진 결과를 실시간으로 반영하도록 설계되었다. 또한, 제안된 시스템은 모바일 단말기의 무선 네트워크 및 기기 특성에 따른 제약 문제로 지하공간 통합지도를 glTF 포맷 형태로 전송 후 가시화 하도록 구현하였다. 구현된 모바일 서비스 시스템은 지하공간 탐사 현장에서 3차원으로 지도 및 공간 객체들을 가시화하여 사용자에게 정확하고 통합된 지하공간 데이터를 제공함으로써 탐사 현장에서의 사고 발생을 방지할 수 있다. 그리고, 갱신된 지하공간 데이터를 실시간으로 지하공간 통합지도 관리 시스템에 전송하여 최신성과 정확성을 유지할 수 있다.
