Question

QUESTION 3 (40 Points) A concrete cantilever retaining wall is shown in the figure below. Using Rankine's Theory for the earth pressures, check stability against overturning and sliding. CLEARLY STATE THE REASONS FOR ANY ASSUMPTIONS YOU MAY MAKE. →lak Ground level I=I =//= y = ? 0 = ? c=0 Unit weightconcrete =24kN/m Pp=0 | 7 m 721211 Pick your own input data for the variables a, b,d,e, f such that a<f and that all the dimensions will make sense and fit well with the already given 7 meter dimension considering the scale visually. For q, surcharge on the backfill, pick a random value between 5 and 25 kN/m². For gamma, soil density, pick a random value between 10 and 30 kN/m". For phi, soil internal angle, pick a random value between 15 and 40 degrees. IF YOUR VALUES ARE SUSPICIOUSLY SIMILAR TO ANOTHER STUDENT'S VALUES, YOU WILL NOT GET ANY CREDIT FOR THIS QUESTON!
