Block flow slope instability / D.F. Coates and Y.S. Yu.: M38-13/78-10E-PDF
"When structural conditions of a slope do not favour plane shear sliding, or the rock mass is not sufficiently ductile to permit rotational sliding, slope instability, if it occurs, must be due to breakdown of the rock substance. The breakdown would be initiated at points of high stress. After local crushing, the load is transferred to adjacent zones, subjecting them to excessive stress and leading to further crushing. Consequently, crushing of rocks at points of high stress is the pertinent failure mechanism. Rational analysis for this type of slope instability - local crushing or progressive failure - is not fully developed at present and obviously much research work has to be done before a useful engineering tool is established. In spite of this difficulty, however, an analysis procedure with examples is suggested based on a probabilistic approach making use of the best available information on stress conditions in a slope and material properties of the rock mass. This in turn will provide a means of appraising the effects of incremental slope changes on benefits and costs"--Abstract, p. i.
