Follow-up Maintenance System Development for the Forest Erosion Control Structures

산지사방공작물(山地砂防工作物)의 사후관리기술체계설정(事後管理技術體系設定)을 위한 조사연구(調査硏究)

To evaluate damage status and necessities of repair works on the forest-side erosion control structures constructed from 1966 to 1986 in Korea, developmental procedures of erosion control structures from the standard unit-cost tables established by the Forestry Administration every year, existing counter-measures for disaster erosion control system administrated by the government organization and existing status of each structure at constructed site were investigated and analyzed integrally. About 10-15% of the constructed forest erosion control structures were required to be repaired as a result of the investigation. It is actually incapable of repairing the damaged forest erosion control structures caused by excessive run-off and floodings under the existing forest-side erosion control systems. Therefore, it is necessary to put regularly repair erosion control system that will be secured by national budgetary pre-allocation system. Especially, it is also necessary to frame a new system that repair erosion control works by national budget (central government) should be possible for any scale of damages in case of the erosion control projects for the disaster counter-measures. The results of this research could be adopted as important policy data for erosion control policy-making in forest-side in Korea.

1966년(年)부터 1986년(年)까지 시행(施行)한 산지사방시행지(山地砂防施行地)의 사방공작물(砂防工作物)에 대한 파양상태(破揚狀態) 및 복구(復舊)의 필요성(必要性)등을 조사평가하기 위하여 사방설계기준단비(砂防設計基準單費)의 발전과정(發展過程) 및 현장시공지(現場施工地)를 조사(調査)하고 또 현행 재해대책사방제도(災害對策砂防制度)등을 검토(檢討)하였다. 당초 시공(施工)한 사방공작물(砂防工作物)의 약 10~15%가 보수(補修)가 필요하였다. 현재(現在)의 치산정책제도(治山政策制度)에서는 산지사방공작물(山地砂防工作物)이 풍수해(風水害) 등으로 파손(破損)당해도 예산미확보관계(豫算未確保關係) 등으로 인하여 "실제로" 복구불능(復舊不能)하므로 정규적(正規的)인 보수사방제도(補修砂防制度)(국비해대책예산사전확보(國費害對策豫算事前確保))를 신설(新設)해야 될 것이며, 특(特)히 "재해대책사방(災害對策砂防)"인 경우에는 피해규모(被害規模)에 불구하고 국비보수사방(國費補修砂防)이 가능(可能)하도록 제도화(制度化)되어야 할 것이다. 이 연구결과(硏究結果)는 앞으로 우리나라에서의 치산정책방향설정(治山政策方向設定)에 귀중한 정책자료(政策資料)가 될 것이다.
