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.

Question

For any C–U- or U–U-type test, what is the magnitude of excess pore water pressure existing in the soil at shear failure is indicated from?

Expert Solution

Step 1

In the given question, we have to determine the indication of magnitude of excess pore water pressure existing in the soil at shear failure.
