Soil shear strength meaning
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 cementation or bonding of particle contacts. Due to interlocking, particulate material may expand or … 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, grain size and grain size distribution, shape … See more This term describes a type of shear strength in soil mechanics as distinct from drained strength. Conceptually, there is no such thing as the undrained strength … See more A more advanced understanding of the behaviour of soil undergoing shearing led to the development of the critical state theory of soil mechanics (Roscoe, Schofield & Wroth … See more • Civil engineering • Direct shear test • Dynamical systems theory • Earthworks (engineering) • Effective stress 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.
