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.

If there is a layer of sand (lower layer) under artesian pressure (causes upward flow), calculate the excavation height H so that a negative effective stress is not generated at point A and therefore the heaving of the soil at that point. Use a unit weight of water w of 62.43 lb/ft3. Note: In this example we make a similarity with the permeameter with upward flow, therefore, H1=0 since from the bottom of the excavation (Na) upwards it remains dry (pumping is done), H2= 20ft-H, h=12ft-H2.

An exploratory drill hole was made in a stiff saturated clay having a moisture content of 38.9% and Gs = 2.34 as shown in the figure. The sand layer underlying the clay was observed to be under artesian pressure. Water in the drill hole rose to a height of 13.8 ft above the top of sand layer. If an open excavation is to be made in the clay, determine the (a) unit weight of the clay, and the (b) maximum cut before the bottom heaves.
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.
