Question 1
Negative skin friction in a soil is considered when the pile is constructed through a
Question 2
The action of negative skin friction on the pile is to
Question 3
Likelihood of general shear failure for an isolated footing in sand decreases with
Question 4
The results for sieve analysis carried out for three types of sand, P, Q and R, are given in the adjoining figure. If the fineness modulus values of the three sands are given as FMP, FMQ and FMR, it can be stated that
Question 5
Which of the following statement is TRUE for the relation between discharge velocity and seepage velocity?
Question 6
The load-carrying capacity of an individual friction pile is 200 kN. What is the total load carrying capacity of a group of 9 such piles with a group efficiency factor of 0.8?
Question 7
The plate load test conducted with a 75 cm diameter plate on soil subgrade yielded a deflection of 2.5 mm under a stress of 800 N/cm2. The modulus of elasticity of the subgrade soil, in kN/cm2, is
Question 8
In an unconsolidated undrained triaxial test, it is observed that an increase in cell pressure from 150 kPas to 250 kPa leads to a pore pressure increase of 80 kPa. It is further observed that, an increase of 50 kPa in deviatoric stress result in an increase of 25 kPa in the pore pressure. The value of Skempton’s pore pressure parameter B is:
Question 9
A saturated clay stratum draining both at the top and bottom undergoes 50 percent consolidation in 16 years under an applied load. If an additional drainage layer were present at the middle of the clay stratum, 50 percent consolidation would occur in
Question 10
A 1:50 scale model of a spillway is to be tested in the laboratory. The discharge in the prototype is 1000M3/s. The discharge to be maintained in the model test is
