A three-storey building is to be constructed on a sand beach. Ground water rises to a maximum
of 3 m below ground level. The beach sand has the following properties: γd = 17.5 kN/m3
, φ = 32° (Nc = 40,
Nq = 25, Nγ = 30). The maximum column load will be 700 kN. Determine the sizes of footing for depths of 1
m and 2 m using a factor of safety of 3. Settlement are not to be considered. Evaluate the two alternatives
from practical consideration (difficulties of construction and cost).

A three storey structure having a square footprint of 225 m2 is constructed on a clayey deposit. The structure is planned to be supported by square isolated footings having a width of 2m and spaced at 5m center to center. A typical borehole indicates that the soil consists of 2m fill layer at the top (g=17KN/m3) followed by a very stiff clay layer 2m thick (gsat=18.5KN/m3) underlain by a normally consolidated soft clay layer of 4.5m thickness (gsat=17KN/m3) followed by...

A firefighter directs a stream of water toward a burning building from the ground level. The stream of water leaves the ground with Velocity Vi, given that Vi=21.0 m/s and theta initial= 37.5 degrees and the building is 22.5 m away from the release point: How far above the ground is the stream of water hits the building?

. During droughts, water for irrigation is pumped from the ground. When ground water is pumped excessively, the water table lowers. In California, lowering water tables have been linked to reduced water quality and sinkholes. A particular well in California’s Inland Empire has been monitored over many years. In 1994, the water level was 250 feet below the land surface. In 2000, the water level was 261 feet below the surface. In 2006, the water level was 268 feet below...

A rigid strip footing with a width of B is constructed above the ground on a clay deposit, overlying bedrock. The depth of clay layer is H and the water level is at the natural surface. Before construction of the footing, laboratory tests on a saturated clay sample, taken at a depth of B/2 below the ground surface, provided the following properties: Compression Index = Cc , Recompression Index = Cr , Consolidation Coefficient = cv Over Consolidation Ratio =...
