The rise of water table below the foundation influences the bearing capacity of soil mainly by reducing
A). cohesion and effective angle of shearing resistance
B). cohesion and effective unit weight of soil
C). effective unit weight of soil and effective angle of shearing resistance
D). effective angle of shearing resistance
Direct measurement of permeability of the specimen at any stage of loading can be made

B). only in floating ring type consolido-meter
C). both (A) and (B)
D). none of the above
The total discharge from two wells situated near to each other is
A). sum of the discharges from individual wells
B). less than the sum of the discharges from individual wells
C). greater than the sum of the discharges from individual wells
D). equal to larger of the two discharges from individual wells
A normally consolidated clay settled 10 mm when effective stress was increased from 100 kN/m2 to 200 kN/ m2. If the effective stress is further increased from 200 kN/ m2 to 400 kN/ m2, then the settlement of the same clay is
A). 10 mm
B). 20 mm
C). 40 mm
D). none of the above
In a triaxial compression test when drainage is allowed during the first stage (i. e. application of cell pressure) only and not during the second stage (i.e. application of deviator stress at constant cell pressure), the test is known as
A). consolidated drained test
B). consolidated undrained test
C). unconsolidated drained test
D). unconsolidated undrained test
