An oil tank is to be sited on a soft alluvial deposit of clay. Below the soft clay is athick layer of stiff clay. It was decided that a circular embankment, 10 m diameter,with wick drains inserted into the soft clay would be constructed to preconsolidateit. The height of the embankment is 6 m and the unit weight of the soil comprisingthe embankment is 18 kN/m3. The following data are available: thickness of softclay = 7 m, ks = 1 × 10−10 m/s and Ch = 0.6 m2/yr. The desired degree ofconsolidation is 90% in 12 months. Determine the spacing of a square grid of thewick drains. Assume wick drain of size 100 mm × 3 mm and qw = 0.1 × 10−6 m3/s.The flow point distance is 4 m. Assume a half-closed system.

A deposit of cohesionless soil with a permeability of 0.3 mm/s has a depth of 12 m with impervious ledge below. A sheet pile wall is driven into this deposit to a depth of 8 m. The wall extendsabove the surface of the soil, and a 3 m depth of water acts on one side. Sketch the flow net and determine the seepage quantity.

A dam includes a sheet pile "cut off" wall near the toe, installed to 7 ft below the groundline. Water seepage is assumed to be at steady state at this time step shown. At this time, the depth of the upstream pond (headwater) is 5 feet. The groundwater is at the same level as the ground on the downstream/tailwater side. The sand stratum thickness, where water is flowing, is 9 ft thick. The permeability of the sand, in the zone of the flow net, is k=42ft/day, the length of the dam (into the page) is 150 ft, and the unit weight of the sand is γsat=128 lb/ft3 (saturated unit weight of the soil). Use γw=62.4 pcf (unit weight of water) for your calculations, where necessary.What is the factor of safety against a quick condition? (use the dimensions given in the problem state to help estimate lengths, where needed)
The value of k of soil around a sheet pile is 10-6 m/s. The flow net of this sheet pile consists of 5 flow lines and 11 equipotential lines. Determine the rate of seepage (in cm3/s per m) if the difference in the water level is of 4m.
