Adhesion and Cohesion of Water U.S. Geological Survey

Cohesion is the component of shear strength of a rock or soil that is independent of interparticle friction. In soils, true cohesion is caused by following: Electrostatic forces in stiff overconsolidated clays (which may be lost through weathering)Cementing by Fe2O3, Ca CO3, Na Cl, etc. There can … See more During critical state flow of soil, the undrained cohesion results from effective stress and critical state friction, not chemical bonds between soil particles. All that small clay mineral particles and chemicals do … See more • Mohr–Coulomb failure criterion See more WebShear strength parameters such as friction angle and cohesion are of the most important soil's parameters which are used for design and practice in engineering works. The main aim of this paper is investigation of artificial neural networks (ANNs) and multivariate regression (MR) potential for estimation of soil shear strength parameters. bosetu contacts
