WebShear strength of a soil is indicative of its resistance to erosion. Specifically, it is defined as the resistance to deformation by the action of tangential (shear) stress. Soil shear strength is made up of cohesion between particles and resistance of particles sliding over each other due to friction or interlocking. Cohesion is composed of ... WebThe shear strength of soils deter-mines the maximum allowable load which can be applied on it (e.g. maximum footing pressure, embankment height etc.). In the case of cohesive soils the undrained loading condition is the least favorable, so it is the undrained shear strength that governs the bearing capacity. Undrained shear strength (s u) is a com-

WebThe main parameters used in formulating the analysis of the shear strength of soil are the angle of internal friction, the so-called friction angle, and the cohesion.
