  • The primary purpose of this thesis is to offer users for the better surroundings in planning subway wall design through analyzing the Wall Environmental Design at Subway Statiov. As the urban circumstances were developed by the economic growth, the new city plan, re-development evoked the radical changes in the urban circumstances. In processing the industrialization and urban surroundings. This range has enlargened and provided the localism, the function, the purpose with the visual informations. The method of this paper was the spot survey simultaneously the photographing of the mould's size. theme, colour, material, compossitiov. In conclusion, concerning about the artificial and subterranean space, the Wall Environmental Design at Subway Station needs more practial approach in the using the space.

  • Because effect about environmental effect that get to human visually is absolute, ability that mural of subway interior considers relation with space is required. Also, public environment element should be designed must intend agreeableness sex by same traitor effect of quality of the material and color and can be evaluated by cultural inheritance that is powerful enemy same time. Wish to accomplish access as meaning of city environment improvement of wall of subway station or underground space etc. through Japan course South Korea's illustration regarding environment landscaping features that is designed in wall of latest domestic building subway interior in this research. Various and new reading by that study and analyze manufactured wall environment landscaping features recently that could find and was approached in variouser technique, practical use of material than single material and is expressed according to history's special quality and planning know can. Underground space can give agreeableness feel and psychological sense of security by user though expression method, material, color plan etc. consist because is having image blockade enemy. Therefore, wall environment landscaping features of underground space to be cultural value and environment Dija because diversified research that is accompanied in element is gone subway interior space of our country and underground space etc. as new culture space develop be able to must.

  • By measuring concrete temperature and strains of concrete and reinforcing bars throughout gages embedded and also by observing the crack occurrence, this study aims at the characteristics of structural behavior of subway wall structure in associate with concrete ages. The length of 23.5m, thickness of 2.0m of real subway custody line was selected as a representative structure and 7 thermocouples and 6 strain gages were installed to measure the behavior of wall structure. The results were compared and verified with analytical results using MIDAS in order to show their usefulness. It was found that only attachment of strain gages on the surface of reinforcing bars can figure out the timing of crack occurrence and hydration heat program is useful to estimate comparatively exact magnitudes of temperature. Since estimated time of crack occurrence throughout thermal stress analysis depends on the period of transferred thermal stress from concrete to reinforcing bars, however, cracks from naked eyes were identified later than analytical results. Cracks were observed first at the center of wall line and then to the end of line symmetrically.

  • The subway concrete box structure can`t establish expansion joint because of animal power delivery of the subway rail. In this case, As increase of structure volume, it is subjected to cause temperature crack. The temperature crack due to the heat of hydration classified a nonstructural crack. but it has a bad effect on durability of concrete structures. especially, in case of a subway concrete box structure, when a water-proof facilities is beaked on an outer-wall, the water leakage occurs through a penetration crack generated from a wall of the concrete structure too. This paper, for the subway concrete box structure, examined a condition of temperature crack occurrence by a heat of hydration concerned external temperature from analysing by a three dimensional finite element method.

  • This study was conducted to investigate the response of the human body to stress induced by wall recording of subway stations in the city center. The experiment was conducted as a simulation exercise, and six images were selected and produced based on Subway Line 2, a representative underground space in Seoul. The study participants included 24 male and female college students. A three-minute experiment was conducted, during which the participants were shown the control image and green wall image once each. To measure psychological status, the following measurement indicators were used: Semantic Differential, Positive Affect and Negative Affect Schedule and State-Trait Anxiety Inventory. Physiological changes were investigated by tracking participants' heart rate and blood pressure. Results showed that parasympathetic and sympathetic nerves were activated in the presence of the green wall in the subway station. The psychological evaluation analysis revealed that negative affect toward underground space decreased, while positive affect increased. This study found that the green wall in subway stations has a stable effect on the human body, both psychologically and physiologically. In the future, green walls in underground spaces can be used to reduce psychological stress and increase physiological relaxation.

  • In this study, design concepts of Seoul Subway Construction (901∼914) are reviewed in relation to the cases for temporary soil support wall systems which are revealed in highly developed design competitions such as Turnkey and Alternative based on. Especially soil and rock properties, various design schemes for dealing with soil and water pressures, new technology adopted etc are discussed very profoundly and broadly for the better understanding and additional clues for constructing new design technologies.

  • The bigger of concrete strctures by a construct technique improvement, and the increase of the cement quantity which is caused by with use of the high-strength concrete for the load-carrying-capacity and a durability cause temperature cracks by a heat of hydration. The temperature crack due to the heat of hydration classified a nonstructural crack. but it has a bad effect on durability of concrete structures. especially, in case of a subway concrete box structure, when a water-proof facilities is beaked on an outer-wall, the water leakage occurs through a penetration crack generated from a wall of the concrete structure too. This paper, for the subway concrete box strucuture, the use of blended cement, the temperature of air and concrete, control joint, was considered and analysed by a three dimensional finite element method.

  • Horizontal displacement of slurry wall with strut is analyzed using 2-D numerical stress-displacement program, FLAC. Validation of the program results are performed using the pre- and ongoing excavation sections and further displacement is predicted in the stage of strut removal. The result show that the calculated displacement was very close to the measured displacement when 40% in-situ strut preloading is applied to the strut loading of the program considering the horizontal spacing of struts in the field. It was found that construction efficiency can be improved by partially removing the struts before putting slabs in the stage of subway structure construction.
