Surficial slope stability analysis
WebABSTRACT. Slope stability is one of the most important topics of engineering geology with a background of more than 300 years. So far, various stability assessment techniques have been developed which include a range of simple evaluations, planar failure, limit state criteria, limit equilibrium analysis, numerical methods, hybrid and high-order approaches … WebApr 23, 2009 · According to previous studies on the way rain infiltration affects the stability of slopes, rain induces a rise in the groundwater level and an increase in pore pressure, both of which decrease the effective stress and shear strength, thereby resulting in slope failures.
