농업용 저수지의 붕괴 사례 분석을 통한 안전점검체계 취약요소 분석

Abstract

The recent increase in disasters caused by typhoons and torrential rain caused by climate change and extreme weather is acting as a risk factor for collapse of old reservoirs. In Korea, there are 17,106 agricultural reservoirs nationwide, and 85.6% of the facilities have been completed for 50 years or more. Most of the old reservoirs are under the jurisdiction of local governments with a total storage capacity of less than 50,000 m3 and safety management is insufficient. However, in current domestic studies, studies on improvement of safety inspection reflecting the characteristics of small-scale agricultural reservoirs under the jurisdiction of local governments are still insignificant. Therefore, in this study, an improvement plan was proposed that reflects the vulnerable factors of the condition evaluation that analyzed the collapse cases of agricultural reservoirs. It is judged that such improvement of the safety inspection system will reduce the occurrence of damage by securing the safety performance of the old reservoir.
