Abstract

This study exhibits how the stability of slope to trigger landslides is affected by soil density as well as rainfall intensity. Five different slope models were made in a Plexiglas container at differing relative compaction levels, which ranged from 60% to 90%. Eight copper wires were used to measure deformation, and eight tensiometers were installed in the slope to measure suction. The slopes were exposed to a rainfall intensity of 3cm/h until completely saturated. The experimental results showed that the seepage velocity decreases rapidly with an increase in relative compaction. The result of this study can be extrapolated to real slope to asses the stability of actual slope in the area at differing duration of rainfall and intensity.
