Web1. SHEARING RESISTANCE AND STRENGTH OF SOILS The property that enables a material to remain in equilibrium when its surface is not level is called shearing strength. All solids have this property to some extent. Shearing strength is the major structural property of soils. It is this property, which provides supporting ability or bearing capacity, and permits … 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.
