초록
전국에 분포하는 저수지는 총 17,505개소이며, 약 68%에 해당하는 11,970개소가 1960년대 이전에 건설되어 노후화가 심각한 상태이다. 대부분의 노후 저수지는 시공 당시 적절한 설계 및 시공기준부재, 축조재료의 특성파악이 어렵기 때문에 안전관리 측면에서 취약하며, 우기시 빗물을 저류하는 이수 목적으로 운영되어 집중호우 발생 시 대규모 수해의 원인으로 작용할 수 있다. 본 논문에서는 국내 저수지 분포 및 관리현황, 저수지 붕괴지역에 대한 현지조사, 원인분석, 향후 운영 방안 등에 대한 종합적인 분석을 수행하여 노후 저수지 안전관리에 대한 문제점과 개선방안을 제시하고자 하였다.
Abstract
Considering that 68% of the reservoirs in Korea (11,970 out of 17,505 reservoirs) were built in the 1960s or earlier, their potential failure due to aging become a serious concern. Most of the decrepit reservoirs did not follow an appropriate design or construction reference at the time of construction and it is difficult to understand the characteristics of the construction materials, which makes it difficult to ensure safety of the reservoirs during the rainy season. Besides, the large amount of their water storage may cause a serious flood disaster. This study undertakes a comprehensive analysis of the distribution and management of the reservoirs as well as the field survey results of the reservoir collapses. The results of the investigation were used as a basis for discovering problems and suggesting ways to improve the current safety management system of the decrepit reservoirs in Korea.
