Soil Shear Strength at the Structure Interface SpringerLink
WebShear strength is defined as the maximum resistance that a material can withstand when subjected to shearing, and the direct shear test is an experimental procedure that is used … 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 of a soil. It depends on a number of factors, the main ones being: • Orientation … 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 • Typical values of angle of friction for soils • Critical state based soil shear • Critique of elasto-plastic soil shear 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 … 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 churchsuite planning module
