Cohesionless Soil: … WebVarious geotechnical experiments were performed, and test results demonstrate that the small strain stiffness increases with an increase in iron content because of the increased interparticle contact stiffness. ... the effects of iron content on the intermediate strain constrained modulus and on the large strain friction angle are insignificant ...
WebAngle of internal friction for a given soil is the angle on the graph (Mohr's Circle) of the shear stress and normal effective stresses at which shear failure occurs. Angle of Internal Friction, f, can be determined in the laboratory by the Direct Shear Test or … WebNov 19, 2010 · internal fricition angle = 34 degrees angle of repose = 34 degrees AS I am sure you have already concluded, using the same angle of repose as the internal friction angle in Rankine's equation yeilds a very high Ka. A reduction to and angle of repose to just 33.4 degrees yields a Ka almost 20% smaller. I have (2) questions: 1.
