The q-slope method for rock slope engineering

WebbDeveloped the widely applied Q-system of rock mass classification for helping to select tunnel and rock cavern support. Co-developed the non-linear Barton-Bandis shear strength criterion for rock joints. Developed the Qtbm prognosis method and Qslope for selecting stable rock slope angles. Criterion for vertical cliff, mountain wall, and mountain heights … WebbLimit equilibrium analysis methods (LEMs) are one of the basic and old analytical approaches for slope stability analyses that are widely used in slope stability studies because of their simplicity, low complexity in the formulation, and less analysis time.
