Abstract

Seepage and slope stability issues concerning infiltration in unsaturated slopes are investigated and presented. A two dimensional finite element analysis are used to examine the effects of the rainfall intensity on the stability of a slope in the tropical region and to develop a boundary of the rainfall induced slope instability. The Jabiru landslide occurred in March 2007 after severe rainstorm with rainfall amount of 0.8 m in 3 days. Parametric study was performed to find out which cases with respect to rainfall intensity and total rainfall triggering the landslide occurrence. Under a uniform distributed rainfall, duration of rainfall is more significant to cause slope failure rather than the rainfall intensity. For any rainfall intensity, if the duration of rainfall lesser than 4 days, the slope was unlikely to fail. The ratio of rainfall intensity and hydraulic conductivity (I/ksat) greater than one caused rapid change the factor of safety of slope. For a rainfall intensity, I/ksat = 0.25 did not trigger slope failure since the factor of safety was obviously greater than two (FS > 2) for all depth.
