Analysis of the Mobilization of an Unsaturated Infinite Natural Slope Due to Strength Reduction

This work analyses the mobilization of infinite natural slopes that are initially partially saturated. Starting from dry conditions (the water table is assumed to be deep, far slope surface), soil shear strength will decrease when wetting front advances surface. First, geometry failure mechanism can develop because such reduction determined. Second, after causes progressive in strength, slide speed reached minimum determined, obtaining an indicator risk derived failure.
