Question

An unsupported slope of height 15 m is shown
in the figure (not to scale), in which the slope
face makes an angle 50° with the horizontal.
The slope material comprises purely cohesive
soil having undrained cohesion 75 kPa. A trial
slip circle KLM, with a radius 25 m, passes
through the crest and toe of the slope and it
subtends an angle 60° at its center O. The
weight of the active soil mass (W, bounded by
KLMN) is 2500 kN/m, which is acting at a
horizontal distance of 10 m from the toe of the
slope. Consider the water table to be present at
a very large depth from the ground surface.
