Case Study of Braced Wall System with High-strength Steel Pipe Strut

고강도 강관파이프 스트러트 흙막이공법 사례연구

According to develop urban area, the depth and floor area of basement tend to become deeper and larger. Excavation work for basement floor work is very important because its cost take 20% of total construction cost. Therefore, many studies of developing retaining wall system have performed for feasibility and safety in deep excavation work. In this study, new supporting system used high-strength pipe for retaining wall is introduced to reduce the construction cost and improve the safety and constructability by analyzing case study.
