WebFriction angle is an important parameter in the static and dynamic stability analysis of hydraulic fill. It is often not practicable to have the standard penetration or cone penetration test rigs into the underground mines, and as a result, the most common practice is to do direct shear or triaxial tests on reconstituted hydraulic samples in ... WebA comparison of the mechanical response between numerical results and physical experiments was carried out. As a result, the MC model allowed to estimate satisfactorily the stress-strain relationship of the soil for w of 10% and 20%, while HS model exhibited a better approximation for w of 34% in comparison with the MC model.
