“…Commercial software such as Slope/W (Geo-slope Ltd, 2001b) and Seep/W is often used. Other adopted computer programs for slope stability analysis include STABL (Chen et al, 2009) and SVSlope (SoilVision System Ltd, 2010). Various methods of slices were chosen to calculate the safety factor of the slope, for example Bishop's simplified method with circular slip surfaces (Ng and Shi, 1998b;Rahardjo et al, 2001Rahardjo et al, , 2007Tsaparas et al, 2002), Morgenstern and Price's method (Blatz et al, 2004;Cascini et al, 2010), and Janbu's method with non-circular slip surfaces (Wilkinson et al, 2002).…”

Rainfall is one of the most significant triggering factors for slope failures in many regions around the world.Numerous research studies have been conducted to investigate infiltration of rainwater into a slope, and the effect of water infiltration on slope stability. In this paper, a review of existing research on infiltration analysis and slope stability analysis under rainfall infiltration is presented. Studies on infiltration analysis with conceptual models, analytical analysis and numerical modelling are first reviewed. The typical pore water pressure profiles in the slope are then discussed. Subsequently, recent developments in analyses of slope instabilities under rainfall conditions using the limit equilibrium method and coupled hydro-mechanical modelling are summarised, and major findings on critical hydrological factors related to rainfall-induced landslides are summarised and discussed. Finally, several research topics are suggested for further study.

“…As a main inducing factor of slope failure, the influence of rainfall on the stability of slope has been studied by many researchers (Brand et al 1984;Larsen 1993;Buma and Dehn 1998;Wasowski 1998;Dai and Lee 2001;Ibsen and Casagli 2004;Li et al 2008;Chen et al 2009;Muntohar and Liao 2009;Dahal et al 2009). However, it is difficult to understand and assess the influence of precipitation on a large-scale landslide that is of complex geological conditions.…”

By employing a complete observation system, the underground erosion in a typical large-scale crystalline schist landslide in Japan, the Zentoku landslide, was studied. It was found that the seasonal heavy rainfall is the main factor leading to the massive underground erosion. Two types of sediment discharge of the landslide were defined. Monitored data indicated that the movement of Zentoku landslide could be affected by the underground erosion following the concentrated heavy rainfall. The influence of the underground erosion on the movement of the landslide presents different features. For the sliding block of shallow and medium depth shear zones (5-20 m), the influence of the underground erosion is most outstanding, while it is negligible for the sliding block of thick soil and rock layers ([30 m). Finally, the rainfall thresholds for the Zentoku landslide, which concern the groundwater state, underground erosion and movement of sliding blocks, were provided to further establish the warning and evacuation system.
