강섬유를 이용한 CS-H 벽체의 성능 평가에 관한 연구 = Study on the Performance Evaluation of CS-H Wall composed of Steel Fiber

국문 초록 (Abstract)

본 연구에서는 국내에서 30m 이상인 대심도에서 강성이 큰 CS-H벽체를 만들기 위하여 지반신소재를 이용하였으며 지반신소재의 혼입율과 슬럼프(슬럼프 플로우) 값에 변화를 주어 현장여건에 맞는 배합을 실시하였으며 목표 슬럼프 180mm 및 슬럼프 플로우 500mm에서는 초기 휨강도, 장기 거동특성 및 탄성계수의 역학적 특성과 동시에 경제성을 모두 만족할 수 있는 배합을 확인하였으나 슬럼프 플로우 600mm에서는 역학적 특성 및 초기, 장기 거동특성에서 취약한 결과를 보였다.

다국어 초록 (Multilingual Abstract)

In this study, CS-H walls with large stiffness were constructed using geosythetics for use in excavation at a depth of 30m or more in Korea, and in order to construct the CS-H wall suitable for the site conditions, the formulation was examined according to the change in the mixing ratio of the geosythetics and the slump value (slump flow) and as a result, in the target slump 180 mm and the slump flow 500 mm, the formulation was confirmed to meet the mechanical properties such as the initial bending strength, the long-term behavior, and the elastic modulus as well as the economic efficiency. However, in the slump flow 600 mm, the result indicated that the formulation was inappropriate in the mechanical properties such as the initial bending strength, the long-term behavior, and the elastic modulus.
