초록

국립공원공단에서는 낙석위험지역에 낙석방지시설(낙석방지망, 낙석방지울타리, 피암터널 등)을 설치하거나 우회탐방로를 개설하는 등 안전 환경 조성을 위한 노력을 하고 있다. 그러나 기후변화에 따른 집중호우나 겨울철 이상 고온, 지반의 노령화로 인한 풍화와 절리현상으로 매년 낙석 발생이 증가하는 추세이며, 기존 낙석위험지역 관리방안에 대한 개선의 필요성이 대두되었다. 본 연구에서는 우리나라 국립공원 중 치악산 국립공원 황골지구를 대상으로 하여 낙석 발생의 위험이 있는 시범지역을 선정한 후 Rockfall 프로그램을 이용한 낙석 분석을 수행하였으며, 분석 결과에 따라 시범지역에 계측시스템과 결합한 대책공법을 적용하여 모니터링을 실시하였다. 이를 통해 낙석의 지속적 관리와 모니터링을 위한 낙석 관리방안을 제시하였다.

The National Park Service is making efforts to create a safe environment by installing rockfall prevention facilities (rockfall prevention nets, fences, and Piam tunnels) in areas at risk of falling rocks. However, the occurrence of falling rocks is increasing every year due to torrential rains caused by climate change, abnormal temperatures in winter, and aging of the ground, and the need to improve the existing rock risk area management plan has emerged. In this study, a pilot area at risk of falling rocks was selected for the Hwanggol district of Chiaksan National Park among Korean national parks, and rockfall analysis was performed using the Rockfall program, and monitoring was conducted by applying a countermeasure method combined with the measurement system to the pilot area. Through this, a rockfall management plan was proposed for continuous management and monitoring of rockfall.
