Resistivity monitoring data at embankment dams are affected by the seasonal temperature variation. Especially when the seasonal temperature variation is large like Korea, the temperature effects may not be ignored in the longterm resistivity monitoring. Therefore, temperature effects can make it dif...

물리탐사법이란? | 물리탐사법은 1960년대 이후에 저수지 안전진단의 한 방법으로 도입되었으며, 초기에는 주로 지온 탐사, 자연전위 탐사가 사용되었다(Ogilvy et al., 1969). | |
전기비저항 탐사가 도입된 이유는? | , 1969). 이후 누수 구간의 전기비저항이 낮다는 사실에 근거하여 전기비저항 탐사가 도입되어 누수 구간의 탐지에 적용되었다(Butler and Llopis, 1990;Johansson and Dahlin, 1996; Titov et al., 2000). | |
CEATI에서 출범시킨 연구그룹이 착수한 프로젝트는? | 1999년 CEATI (Center for Energy Advancement through Technical Innovation)는 댐 및 저수지 안전진단에 대한 워크숍(International Diagnostics for Embankment Dams)을 개최하고, 제체 붕괴의 원인이 되는 누수 구간 탐지에 지온, 자연전위, 전기비저항 및 탄성파 탐사 등각종 물리탐사법의 개발 및 적용을 위한 연구 그룹 DSIG (Dam Safety Interest Group)를 출범시켰다. DSIG에서는 제체의 내부 침식, 세굴에 의한 누수 구간의 효과적인 탐지를 위한 각종 물리탐사법의 개발 및 적용을 위한 국제 프로젝트에 착수하였으며, 이 프로젝트를 통하여 저수지 누수 구간의 조기 탐지를 위한 다양한 물리탐사 방법이 체계적으로 개발되고 활발히 적용되기 시작하였다. 이후 2. |
