A 6m. tall cantilever wall retains soil that has the following properties. C = 0 phi = 30 degrees and soil weights 19.2kN/m3. The ground surface behind the wall is inclined at a slope of 3hor. To vertical and the wall has moved sufficiently to develop the active condition. Determine the normal force acting on the back of the wall using Rankines’ Theory.
Hint: Arc tan 1/3 = 18 degrees and Ka = 0.399
Solution:
