As the urban population continues to increase, cities grow through the expansion of high-rise and high-density residential areas, which demand good living environments to improve citizens’ quality of life. This study is based on the apartment type proposed by Moon Soo-young(2011) in accordance with the layout pattern of green spaces in three apartment complexes located in Dalseo-gu, Daegu Metropolitan City. The purpose of this research is to discover the causes of the high nutritional rate and successful planting method, as well as to suggest a plan to improve the planting structure(general complex, built apartment). According to the study results, the green area ratio of the study was the highest with 44.7% of the total area, followed by Wolbahil state(center type) with 30.3%, and the Bible Jeongnam Town(type of arrangement around buildings) with 27.3%. Shared facility centers were placed outside the apartment buildings in common with the type of arrangement around the buildings and the type of centering arrangement, and the coverage rate in the apartment complexes increased. There are many underground parking lots in the vicinity of the buildings; the center type of the buildings and the parking lots for the disabled are located underground. In general, residents use the underground parking lot, and the ground greenery ratio is higher than other types. Through the analysis of the facilities in the complex according to the type, we found the cause of high green ratio and good planting method and suggested an improvement plan for the general and constructed apartments. In the general apartment complex improvement plan, it is possible to increase the green area by minimizing the single-story buildings such as the shared facilities center and arranging these facilities in the apartments. The number of entrances is reduced due to the connectivity between underground parking lots. Reducing the area of the road within the complex can reduce the number of green spaces. It is important that water pipes are laid mainly under broad-leaved trees and that the plant structure is multi-layered. In order to estimate the construction of the apartment, we propose a method to construct the green space in three dimensions by using methods such as wall greening and rooftop greening. It is possible to utilize enough spaces to waste through the plant materials. In the plant structure, a cluster planting was arranged and the shrubs and plants were placed in the complex.

해양암반이나 구조물 해체를 위한 전통적인 방법은 다이나마이트를 이용한 발파공법, 잭해머(Jackhammer)를 이용한 공법이다. 이러한 방법은 소음이나 폭발의 위험등으로 인해 사용에 많은 제약이 따른다. 이런 제한된 상황에서 사용할 수 있는 무소음화학팽창제(SCDA)의 사용이 증가하고 있는 추세이다. 그러나 무소음화학팽창제의 사용에 관한 규격이나 설계 및 시공에 대한 제안서는 현재 전무한 상황이다. 따라서 본 연구에서는 다양한 조건(구조물의 구속, 천공홀의 크기, 천공홀의 수 등)에서 콘크리트 구조물에 균열이 생성, 진전될 수 있는 최소요구팽창압을 예측하였다.
