Abstract

Abstract

Based on the global method of stability analysis for stopes, a method to consider the effect of anchor reinforcement on slope stability was proposed, in which anchoring forces were assumed to be borne by the whole sliding body instead of individual slices as a concentrated force,the formula for safety factors of anchored slopes was deduced. As the equilibrium conditions were formulated in terms of the whole slip body instead of individual slices, the internal forces in slopes were more authentic. Simultaneously, three equilibrium equations for moment were formulated according to the global moment equilibrium conditions rather than the traditional equilibrium equations for forces in horizontal and vertical directions and one moment equilibrium equation. Therefore, the method was not only suitable for slopes with slide surfaces with different shapes,but also possessed more excellent numerical properties. Finally,three classical examples were given to prove the effectiveness of the method.
- slope,
- stability analysis,
- global method,
- limit equilibrium method,
- anchor
