A sand layer found at sea floor under 20 m water depth is characterised with relative density = 40%, maximum void ratio = 1.0, minimum void ratio = 0.5 and specific gravity of soil solids = 2.67. Assume the specific gravity of sea water to be 1.03 and the unit weight of fresh water to be 9.81 kN/m3.

What would be the effective stress (rounded off to the nearest integer value of kPa) at 30 m depth into the sand layer?

Assume the specific gravity of sea water to be 1.03 and the unit weight of fresh water to be 9.81 kN/m3.

What would be the change in the effective stress (rounded off to the nearest integer value of kPa) at 30 m depth into the sand layer if the sea water level permanently rises by 2 m?

Direction: The unconfined compressive strength of a saturated clay sample is 54 kPa.

The value of cohesion for the clay is

Direction: The unconfined compressive strength of a saturated clay sample is 54 kPa.

If a square footing of size 4 m x 4 m is resting on the surface of a deposit of the above clay, the ultimate bearing capacity of the footing (as per Terzaghi’s equation) is

Percentage finer than 4.75 mm = 60

Percentage finer than 0.075 mm = 30

Liquid Limit = 35%

Plastic Limit = 27%
