a）For clays, the failure line (one that connects the peak failure stresses) in the normally consolidated range does not have a cohesion intercept, whereas the failure line in the overconsolidated range has a cohesion intercept. T or F B）During the shearing phase of a CU test, the void ratio of a NC consolidated clay specimen will: 1 decrease. 2 could increase or decrease. 3 remain a constant. 4 increase. C)What does the cohesion (that appears in the Mohr-Coulomb criterion) of OC clays depend on? 1the preconsolidation pressure. 2whether the failure stresses are total or effective. 3the soil type. 4everything listed here.

Test for Determination of Shear Strength

The term shear strength is often associated with the soil. Shear strength is defined as the resistance to the deformation of soil particles due to the continuous action of shear stress. In short, shear strength is the maximum shear stress that a soil can sustain.
