Abstract

In geotechnical and civil engineering, capillary barrier systems (CBS) are widely utilized to prevent rainfall infiltration and improve the stability of soil structures. This study evaluated the infiltration characteristics of CBS through small-scale model tests and infiltration analysis. The data conform that the performance of CBS is influenced by the slope angle and the thickness of the finer-grained layer, and that CBS can reduce rainfall infiltration on slopes. However, the performance of CBS decreased as the rainfall intensity increased. This study provides fundamental data for the design and optimization of CBS and suggests their potential application on slopes.

모세관 방벽 시스템(Capillary Barrier System, CBS)은 토목 및 지반공학 분야에서 강우 침투를 제어하고 토양 구조물의 안정성을 향상시키기 위해 널리 사용되고 있다. 본 연구에서는 소규모 모형 토조 시험과 침투 해석을 통해 CBS의 침투 특성을 평가하였다. 경사 및 세립토층 두께가 CBS의 성능에 영향을 미치는 주요 인자임을 확인하였으며, CBS를 통하여 비탈면의 강우 침투를 억제할 수 있다는 것을 확인하였다. 하지만, 강우 강도가 증가할수록 CBS의 성능이 다소 저하되는 경향을 보였다. 본 연구에서는 CBS 설계 및 최적화를 위한 기초 데이터를 제공하였으며, 실제 비탈면에 강우 침투 방지 시스템으로서 CBS 적용에 대한 가능성을 제시하였다.
