최대 강수량의 증가와 집숭호우 등 재난재해로 인해 농업용 시설물의 피해가 잇따르고 있으며, 최근발생한 사례를 살펴보면 안전진단 등급이 B 또는 C 임에도 불구하고 손상 및 붕괴사례가 발생하고있다. 농업용 댐의 안정적인 기능을 수행하기 위해서는 주기적인 유지보수가 필수이며 긴급출동 및초기대응을 하기 위한 상황에 적합한 의사결정을 하는 것이 중요하다. 따라서 우선 안전관리대상을식별하고 관리기관과의 접근성을 고찰하는 것이 필요하다. 이 연구는 한국농어촌연구원의 농업용 댐을대상으로 우선 안전관리대상 1,467개를 선별하고 공간 네트워크 분석을 수행함으로 지역별로 관리 접근성을 살펴보았다. 또한 관리 지점을 추가 설정함으로 접근성의 변화를 분석해보았다. 그 결과 전체시간은 5,207분(18.6%) 감소하였으며, 평균 시간은 4분(21.1%) 감소함을 확인할 수 있었다. 분석결과를통해 전국에 분포된 농업용 댐의 안전성 강화와 효율적인 관리체계를 확립하기 위한 기초자료로 활용될수 있다고 판단되며 비효율적으로 관리되어 발생할 수 있는 문제들을 해결하는 계기로 작용해보길기대해본다.
Abstract
Due to the long monsoon season and heavy rainfall, domestic agricultural dams in South Korea are suffering severe damages. Recent incidents indicate that damage and collapse of agricultural dams are occurring regardless of their safety assessment grades. To ensure the stable performance of agricultural dams, regular maintenance is essential. Moreover, it is crucial to make quick decisions in crisis situations for emergency response and initial actions. Therefore, it is necessary to prioritize safety management targets in advance and assess the accessibility of sites and management agencies. This study selected 1,467 priority safety management targets for agricultural dams managed by the Korea Rural Community Corporation and conducted spatial network analysis to examine the accessibility of sites by region. Additionally, the change in accessibility was analyzed by adding management points. The analysis results can be utilized as fundamental data for enhancing the safety and establishing an efficient safety management system for agricultural dams distributed nationwide.
