Question

An oil storage tank 35min diameter is located 2m below the surface of a deposit of clay 32mthick, which overlies
a firm stratum, as shown in the scheme below. The net foundation pressures at the foundation level equal
105 kN/m². The average values of mv and pore pressure coefficient A for the clay are 0.14 m²/MN and 0.65,
respectively. The undrained value of Young’s modulus is estimated to be 40 MN/m². Determine the total settlement
(excluding settlement due to secondary compression or creep) under the centre of the tank.
