Unformatted text preview: (c) How do the effective stresses calculated in parts (a) and (b) compare? 4. A 50 foot thick deposit of gravel overlies bedrock. The gravel has a void ratio of 0.42 and the specific gravity of solids is 2.65. The water table is at the ground surface. (a) Plot the vertical effective stress vs. depth in the gravel. Plot the stresses as you were instructed for Problem 10.8 in Coduto, i. e. plot depth on the vertical axis with zero at the top and depths increasing downward. (b) A wide earth fill is slowly constructed on the gravel. The fill is 15 feet thick and has a total unit weight of 125 lbs./cu.ft. The water table remains at the elevation of the original ground surface. Plot the effective stress vs. depth in the gravel after the fill is placed. Plot these data on the same plot as the one for effective stress before fill construction....
