Q.3. A cut slope was excavated in a saturated clay with a slope angle β = 57 ͦ with the
horizontal. Slope failure occurred when the cut reached a depth of 8 m. Previous soil
explorations showed that a rock layer was located at a depth of 2 m below the ground
surface. Assuming an undrained condition and that ɣsat = 19 kN/m3
:
Determine the undrained cohesion of the clay (Fig 3).
What was the nature of the critical circle?
With reference to the top of the slope, at what distance did the surface of the sliding
intersect the bottom of the excavation?
