Q2. The sand (Gs = 2.65) in a deep natural deposit has an effective angle of internal friction of 37 and a dry unit weight of 17 kN/m. Calculate the shear strength of the sand at a depth of 6 m below the ground surface for the following conditions: a). The GWT is at a depth of 3 m below the ground surface. (Hint: assume the sand is dry above the GWT.) b). The GWT is at the ground surface. Q2.
