황령산 사면 계측관리 분석에 관한 연구 = Study on analysis for the slope menitoring performance at the Whangryeong mountain site

다국어 초록 (Multilingual Abstract)

Landslide of the Whangryeong Mountain which was occurred at Busan Metropolitan City in 1999 belongs to the category of plane failure. Automatic monitoring system to measure horizontal displacement, pore pressure change and load change has operating from reconstruction stage for evaluating rock slope stability(August, 2000~Feburuary, 2002). As a result of the analysis on the monitoring performance data, it is suggested that infiltrated rain water from ground surface discharges rapidly through cut-slope because pressure head of water decreases rapidly after rainfall while rise of pore pressure is proportional to the amount of rain water. As a result of data analyses for inclinometers and load cells, it seems that slope is stablized because ground deformation is rarely detected. The areas especially similar to the study site where landslide is induced by heavy rain fall, change of pore pressure is rapidly analyzed using automatic monitoring system. Therefore, it is considered that automatic monitoring system is very effect for slope stability analysis on important cut-slopes.
