Analysis of methods for evaluation of soil shear strength parameters

Abstract

Having performed an analysis of the methods for identifying a soil shear strength one can find four different coordinate systems for evaluating the soil shear strength parameters. It is stated that a theoretical functional relation exist for the shear strength parameters, have been identified via different evaluation methods. Thus one must obtain the same final parameters of shear strength. The investigation is assigned to identify reasons of obtained differing magnitudes of the shear strength parameters via triaxial testing by employing the used in practice methods. The method to identify angle of internal friction and cohesion satisfying all four coordinate systems is proposed.
