Overstressing of a slope or reduction in shear strength of the soil may cause rapid or progressive displacements. Stability analysis of a rock slope requires assessment of shear strength parameters, that is, cohesion (c) and angle of internal friction of the rock mass. Dilatancy in a rock mass is unconstrained near slopes as normal stress on joints is small due to weight of the wedge.

Jan 01,  · Soil deterioration is one of the main causes of slope failure in hard clays and clay shales, but so far a clear general framework of the causes of deterioration is still missing.

One of their characteristics is that the mobilized shear strength corresponds to the residual strength. The residual friction angle of clays depends on pore fluid composition which, in formations of marine origin, could have changed after emersion from the sea because of a number of processes, e.g., contact with rain Cited by: Factors influencing determination of shale classification indices and their correlation to mechanical properties Henkel, D.J.

Jun 06,  · Stability of slopes is a topical and substantial issue, affecting areas where there are natural slopes as well as man-made slopes in urban areas, e.g. railway and road embankments, deep excavations or dams [1, 2, 3].In these all cases, there are a large number of factors influencing the final safety factor Łukasz D.
