As a consultant engineer, you are given a slope design task. A cut slope was excavated in a saturated clay with a slope angle, β=35∘, with the horizontal. Previous soil explorations showed that a rock layer was located at a depth of 15 m below the ground surface. Assuming an undrained condition and γ= 18.7kN/m3 and the undrained cohesive value, cu​=75kN/m2: Assume D= 1.5. The task is given as follow;
(i) Analyze the maximum height of the slope can be cut. (3 marks) (ii) Identify the nature of the critical circle failure. I (3 marks) (iii) With reference to the top of the slope, plan your working area of the slope analysis by using slope software.
