A new failure mode chart for toppling and sliding with consideration of earthquake inertia force

摘要

Rock slope failures involving single plane sliding or toppling have been studied extensively in the past. The problem has typically been formulated for the case of a block on an inclined plane. The model of a block on an inclined plane can help simulate many problems in rock slope engineering: it can be used to represent finite rock blocks formed by intersections of steeply inclined joints and shallowly inclined bedding planes and thus it can sometimes be used to simulate landslides or rock slides. The simplicity of the model and its attractive applicability calls for development of analytical solu- tions as these are quite useful in practice.
