A soil profile at the site of a partially buried steel water tank of a large diameter consists of: 0-10m Y-18kN/m³ (Both above and below the water table) 10-13m Y=16kN/m³ 13m + The water table is at a depth of 2m and tests on a sample taken from the mid-depth of the clay gave a moisture content of 29%. Consolidation testing positions gave the following properties: Ce=0.5 C 0.1 o'pc=140kPa Construction of the tank will initially involve Sand lowering the water table to a depth of 9m, excavating 8m of sand and placing and filling the tank to give the situation shown in the figure. Determine the thickness of the clay layer a long time after construction for 2 cases: Sand Clay Rock Water table 14m Water tank Clay Rock 12m 7m 1m 3m a) Assuming that the water table is permanently maintained at the lower level. b) Assuming that the water table is allowed to rise back to its original position immediately after construction (before starting the consolidation process of the clay layer). Note that you should use a one-point calculation based on conditions at the mid-depth of the clay. You should also assume that the tank is permanently full and that the weight of steel in the tank is negligible compared to the weight of water.
