Question

Please answer 15.12

15.12 For the cut slope described in Problem 15.11, how deep should the cut be made to
ensure a factor of safety of 2.5 against sliding?

15.11 A cut slope is to be made in a saturated clay. Given: The undrained shear strength,
c, = 26 kN/m? (4 = 0 condition), and y = 18.5 kN/m'. The slope makes an
angle, B = 55° with the horizontal. Assuming that the critical sliding surface is
circular, determine the maximum depth up to which the cut could be made. What
is the nature of the critical circle (toe, slope, or midpoint)?
