Two fuel storage tanks will be placed at an oil refinery nearBakersfield. The tanks are 10 m in diameter, are spacedcenter-to-center at 15 m, and contain fuel that has a Gs=0.95. Theheight of the fuel in the tanks is 4 m. Determine the stress changein the soil below the tanks at 4 locations: a) beneath thecenterline between the tanks, b) beneath the edge closest to theother tank, c) beneath the center of one tank, and d) beneath thefar edge of the tank. These calculation need to be carried out fora depth of 10 m. Assume the base of the tanks rests on the groundsurface (no embedment), that the water table is very deep, and theunit weight is 18 kN/m3 .
