Question 41137

posted 1 years ago

You have developed the preliminary design for a gravity retaining wall (shown below), which must have a minimum factor of safety against sliding = 1.5 and a minimum factor of safety against overturning = 1.75. Additionally, the average bearing stress must be less than the allowable bearing capacity of 2,500 psf. Which of the criteria listed above are or are not satisfied by this design? Support your answer with calculations. Extra Credit (+5 pts): What is the minimum width of the base so that the failed failure criterion is satisfied?
