Paper Number: ISRM-IWVE-2010-021
..., with high peak strengths and significantly lower residual strengths. In the case of hydrothermal alteration, the weakest units are porous, silty, clay-rich, medium plasticity soils (MH) with low cohesion values and varying angles of internal friction (17–45°). Secondary mineralogy produced by...

.... However, a mixed type can be defined in most cases, when both kinds of void are present. At other times, the pyro-clasts do not exhibit any kind of "macroporosity". An extensive study of how the type of porosity may affect the strength of the material is being carried out at CEDEX geotechnical laboratory...

... strength index (GSI) and textural features were used to deduce geomechanical parameters of rock massifs. This paper discusses the changes in cohesion and friction angle as a function of the slopes height for different rock massifs and geological conditions expressed in the form of GSI.
