Abstract

Effective urban flood reduction and restoration of natural water cycle at present include the application of permeable pavements. The application of permeable pavement addresses urban water cycle and disaster related events which gained attention internationally. However, few researches have been conducted to investigate unsaturated behavior and evaluate the water characteristics curves of these type of pavement materials most especially in the unsaturated state. In this study, first the saturated permeability and the soil-water characteristics curve of a pervious concrete are evaluated based on laboratory tests, and, based on experimental results, the infiltration of permeable pavement system is numerically modelled. In the soil-water characteristics curve of a pervious concrete, the volumetric water content drops very steeply after the air entry value with increasing matric suction. From the finite element analyses, the performance of the permeable pavement when compared to impermeable pavement, confirmed that the whole system effectively delayed and reduced runoff.

효과적인 도심 홍수 감소 및 물순환 기법 중 하나로 투수성 포장의 적용을 들 수 있다. 도심 물순환 및 방재를 위한 수단으로 투수성 포장의 적용은 국제적으로 점차 확대되고 있는 실정이다. 투수성 포장 내의 침투는 대부분의 경우 불포화 상태에서 시작하나, 현재 투수성 포장재의 흙-수분특성 곡선의 산정 및 이를 바탕으로 한 투수성 포장 시스템의 침투성에 대한 연구는 거의 찾아볼 수 없다. 본 연구에서는, 먼저 실내시험을 통해 투수성 포장재의 포화투수계수와 흙-수분특성곡선을 산정하고, 이를 바탕으로 유한요소해석을 통해 강우시 특정 투수성 포장 시스템의 침투특성 및 홍수 저감 효과를 분석하는 것을 그 목적으로 한다. 실험에 사용된 현장 투수성 콘크리트 시료의 흙-수분특성곡선은, 모관흡입력이 증가함에 따라 공기 유입 후 체적함수비가 상대적으로 급격하게 감소하였다. 유한요소해석 결과로부터, 불투수성 포장과 비교하였을 때, 즉 강우가 침투 없이 바로 유출이 되는 경우와 비교하여, 투수성 포장 시스템의 노반으로 침투가 불가능한 경우에도, 투수성 포장 시스템이 강우의 지표유출을 효과적으로 지체 및 감소시키는 것을 확인하였다.
