The shear strength of soil depends on the effective stress, the drainage conditions, the density of the particles, ... It is commonly approximated using the Mohr-Coulomb equation. (It was called "Coulomb's equation" by Karl von Terzaghi in 1942.) (Terzaghi 1942) ... See more Shear strength is a term used in soil mechanics to describe the magnitude of the shear stress that a soil can sustain. The shear resistance of soil is a result of friction and interlocking of particles, and possibly … See more The stress-strain relationship of soils, and therefore the shearing strength, is affected (Poulos 1989) by: 1. soil composition (basic soil material): mineralogy See more The drained shear strength is the shear strength of the soil when pore fluid pressures, generated during the course of shearing the soil, are able to dissipate during shearing. It also applies where no pore water exists in the soil (the soil is dry) and hence pore fluid … See more • Civil engineering • Direct shear test • Dynamical systems theory • Earthworks (engineering) See more This term describes a type of shear strength in soil mechanics as distinct from drained strength. Conceptually, there … See more A more advanced understanding of the behaviour of soil undergoing shearing led to the development of the critical state theory of soil … See more A refinement of the critical state concept is the steady state concept. The steady state strength is defined as the shear strength of … See more WebLandslides in residual soil slopes are commonly induced by rainfall infiltration. These residual soils are typically in an unsaturated state with negative pore-water pressures or matric suctions since the groundwater tables in steep slopes are often deep. The net normal and shear stresses of the soil remain essentially constant during rainwater infiltration into …
