Abstract

The information of cut slope in Mt. Jang area, Busan is investigated in order to construct the Slope Management System in Urban Area. The slope inspection sheet is made to record the characteristics for cut slopes, and that is capable to be inputted slope information systematically. The cut slopes in Mt. Jang area are consisting of 69 slopes. Most of the cut slopes are constructed in cutting slope and retaining wall (CR). The cut slopes located in housing facilities are 46 slopes, and the slopes located in school facilities are 12 slopes. The traverse of cut slopes is mainly ranged from 50 m to 150 m, and the height is mainly ranged from 10 m to 20 m. The slopes combined with soil and rock are mostly distributed. The retaining wall was installed in the toe part of cut slope in order to increase the slope stability, and the additional reinforcement methods including the anchor, drainage, preventing rock fall, shotcrete and vegetation were installed at the toe part of cut slopes.

본 연구에서는 대도시사면 통합관리시스템 구축을 위하여 부산 장산 지역의 절개사면에 대한 현황을 조사하였다. 절개사면에 대한 특징들을 기록할 수 있는 조사용 사면 조사용 시트를 작성하였으며, 조사시트에는 사면정보를 체계적으로 기재할 수 있도록 하였다. 부산 장산 일대의 절개사면은 총 69개소로서 대부분이 옹벽과 사면으로 이루어진 사면(CR)이다. 절개사면에 인접하고 있는 시설물로는 주거시설이 46개소, 학교가 12개소로 조사되었다. 그리고 절개사면의 평균 연장길이는 50m에서 150m로 분포하고, 높이는 10m에서 20m로 분포한며, 토층과 암반층이 혼재된 혼합사면이 가장 많이 분포하고 있다. 사면의 안정성 확보를 위하여 대부분 사면하단부에 옹벽이 설치되어 있으며, 옹벽 및 절개사면의 추가적인 안정성을 확보하기 위하여 앵커공, 배수공, 낙석방지공, 숏크리트공, 식생공 등이 보강되어 있음을 알 수 있다.
