수압을 받는 콘크리트의 투수성에 관한 연구

Abstract

본 연구에서는 이러한 배경하에 고압을 받는 내압법에 의한 콘크리트의 투수 실험 및 기존 논문 조사를 통하여 콘크리트 투수계수를 파악한 후, 이를 침투확산률 해석에 적용함으로써 수압을 가한 경우의 콘크리트 내부로의 수분 침투를 해석적으로 검토하였다.

The watertightness of concrete is judged by the depth of penetration of water forced in under pressure with the mechanism of flow of seepage water examined theoretically and experimentally. As a result, it is found that in the case of low water pressure approximately 0.15Mpa or less, the flow is Darcy seepage flow, the same as flow in an ordinary sand stratum, whereas in the case of high water pressure, the flow is diffused seepage flow accompanied by internal deformation of concrete. It is suggested that the watertightness of concrete be evaluated by seepage coefficient in the case of the former and diffusion coefficient in the case of the latter
