WebThe triaxial shear test is the most versatile of all of the methods for testing the shear strength of soil and finding its cohesion (c) and angle of internal friction (φ). It can measure the total, as well as the effective stress parameters, and can be conducted on any type of soil. Drainage conditions can be controlled, and pore water ...

WebTheoretically a pure clay would have a value of 0° and φ would rise with increasing sand content and density to approximately 40° for a compact sandy loam soil. Loose sands range between 25 to 30°. As pure clays are rarely found in top soils the typical value for a ‘clay’ soil would be in the range 5 to 10°. Angle of Soil-Metal Friction (δ) WebApr 26, 2013 · Hello, When i plot my total stress Mohr's circles for an overconsilidated fat clay (LL=81, PI=58) I get a decent looking diagram with c=3.21 psi and phi = 8.2°. However, when I plot the effective stress Mohr's circles and plot the c'-phi' line tangent to the circles I get c'=10.28 psi and phi' = 8.2°.
