Pore-pressure generation initiating a rainfall-induced landslide: experimental insights and numerical modelling

Key Points

• Landslides are triggered by pore-pressure generated from rainfall, demonstrating a clear link between water saturation and slope stability.
• Findings indicate pore-pressure can increase significantly in saturated conditions, with a rise of 30% observed in controlled tests.
• Experimental insights were combined with numerical modelling to analyze the dynamics of rainfall-induced landslides.
• The implications of this study suggest that understanding pore-pressure dynamics can enhance predictions of landslide events, aiding in risk management.
