Concept explainers

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.

4. A sandy soil sample was subjected to a consolidation pressure of 100 kPa and Consolidated drained test was conducted on it. The failure plane angle which the sample made at failure with respect to horizontal was 60°. Find the vertical stress at failure. If instead of increasing the vertical stress, it was decreased gradually, explain why the sample would fail. Obtain the shear and normal stress at failure for both of these conditions.
