A cut slope is to be made in a saturated clay. Given: The un-drained shear strength, cu = 26 kN/m2 (( = 0 condition), and ( = 18.5 kN/m3. The slope makes an angle, ( = 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)?
