IMPACT OF RAINFALL INFILTRATION ON A GROUND SLOPE

Abstract

In many parts of the world, rainfall is one of the most major triggering causes for slope failures. Rainwater infiltration into a slope and the effect of water infiltration on slope stability have been the subject of several research projects. A review of current research on infiltration analysis and slope stability analysis under rainfall infiltration in Uttarakhand, Almora district. The first section looks at studies on slope stability analysis using conceptual models by using GEOSTUDIO software analysis. Following that, the slope's typical pore water pressure profiles are discussed and recent advances in the use of the limit equilibrium approach to analyses slope instabilities under rainfall conditions and the most important discoveries on essential hydrological parameters related to rainfall-induced slope failure are summarized and addressed. It is currently challenging to assess the impact of rainwater infiltration on slope stability. Infiltration reduces a slope's stability. The failures were caused mostly by the loss of matric suction in the soils caused by precipitation the Lower conductivity soil slope was more influenced than the Higher conductivity soil slope in terms of stability and rate of reduction in factor of safety was regulated by antecedent rainfall patterns In this research work we are computing the slope stability using the Slope/W and seepage analysis using Slope/W method of GEOSTUDIO software parametric study was conducted to investigate the effect on safety factor of slope and result shows that short-term rainfall can change low factor of safety while continuous rainfall can result in the rise of ground water table due to which the slope induced instability.
