대규모 절토사면 유지관리 시스템 운영간 적절한 장소에 합리적인 공법을 선정하여 시공하는 것은 중요한 일이다. 다양한 옹벽 시공 공법이 있지만 시공성과 경제성을 감안할 때 옹벽의 기능을 최대한 유지하면서 친환경 기술을 접목할 수 있는 돌망태 옹벽은 최근 사면 보강에 빈번히 시공되고 있다. 장기간 그 기능을 유지해야하는 옹벽의 경우는 유지관리가 더욱더 중요한 과제이다. 따라서 본 연구에서는 돌망태 옹벽의 시공 및 유지관리 점검에 대한 방안을 사례분석을 통하여 제안하고자 한다.

This study aims to establish a monitoring method for managing the effective maintenance of tailings dams. The monitoring of a tailings dump area involves several parameters and their investigation through a selection of evaluation items. The extents of defects and progressive failures also need to be effectively estimated. Therefore, the monitoring items can be subdivided into categories relating to the retaining wall structure (concrete wall, reinforcing stone wall, mesh gabions) and general facilities (liner, covering soil, slope, tailings, rain protection facility, leachate, planting), and quantitative evaluations can then be conducted for each condition. In doing so, we developed a systematic monitoring method that assesses the dam maintenance condition with grades and scores. The field application of the monitoring method results showed it to provide a more detailed evaluation than existing monitoring methods: the method detected an additional 16 defects missed by conventional methods. The evaluation gave scores of 89.3, 22.2, and 27.8 to the Geumjang mine tailings dam, the Gupoong mine tailings dam, and the Hwachun mine tailings dam, respectively. The advanced method can provide quantitative evaluation and perform detailed monitoring of the dams. This quantitative evaluation can be used to decide on maintenance priorities, select the main management items, and establish schedules of maintenance.
