Abstract

The objective of this study is to evaluate landslide hazard susceptibility and produce the landslide hazard maps for soil slope using checklists as a preliminary investigation method. Tables, proposed by NDMI (National Disaster Management Institute), are applied for slope stability assessment, and are comprised of checklists on soil slopes. Database including engineering properties of soil is constructed through the field survey and results from previous studies for The Mt. Hwangryoeng area at center of Busan. All data related to creating the thematic maps was carried out using ArcGIS 10.0. Results from using this method indicated that soil slope are evaluated from very stable to stable. Moderate stability has been partially presented along the edge of mountain. Results from landslide hazard maps can be used to prevent damage from landslides and facilitate appropriate land use planning.

본 연구의 목적은 예비조사 방법으로서 점검표를 이용하여 토질사면에 대한 산사태 취약도를 평가하고, 산사태 재해위험지도를 만드는 것이다. 국립재난안전연구원이 제안한 표들이 사면 안정성 평가에 적용되었으며, 이 표들은 토질사면에 대한 안정성 점검표로 구성되어 있다. 흙의 공학적 특성을 포함한 자료들은 부산 중심부의 황령산 지역에 대한 현지조사와 기존 연구를 통하여 획득되었다. 주제도를 만드는데 관련된 모든 자료는 ArcGIS 10.0을 이용하여 변환되었다. 이 방법을 사용한 결과 연구지역의 토질사면은 매우 안정-안정 영역에 분포되었으며, 중간 정도의 안정성 영역은 산의 말단부를 따라 부분적으로 분포한다. 산사태 위험도 지도의 결과는 산사태에 의한 피해를 방지하고, 적절한 토지이용계획을 수립하는 데 이용될 수 있을 것이다.
