Solution:
The bearing capacity of a rectangular footing of plan dimensions 1.5m x 3m resting on the surface of a sand deposit was estimated as 600 kN/m2 when the water table is far below the base of the footing. The bearing capacities in kN/m2 when the water level rises to depths of 3m, 1.5m and 0.5m below the base of the footing are
Solution:
A dam which is 20 m high is constructed on an impermeable foundation. The coefficient of permeability of the soil used for the construction of the dam in the horizontal and vertical directions are 4.8 × 10-8 m/s and 1.6 × 10-8 m/s, respectively. The water level on the reservoir side is 18 m from the base of the dam, and the downstream side is dry. It is observed that there are 4 flow channels and 18 equipotential drops. The quantity of seepage per unit length in m3/s is:
