1/9

1/3

Solution:

The precast concrete piles are generally used for a maximum design load of about _____

100 tonnes

70 tonnes

80 tonnes

60 tonnes

Solution:

In soil dynamics problems, the analysis may be conveniently carried out by a ___________

Spring mass system

Inertial force

Free vibration

Amplitude test

Solution:

The allowable load that the pile can carry safely is determined on the basis of

Stability of the pile foundation

All of the mentioned

Factor of safety

Load test

Solution:

According to the IS code, the minimum spacing between piles should be:

2.5 x dia (for point bearing piles)

3 x dia (for friction piles)

All of the above

2 x dia (for loose sand or fill deposits)

Solution:

A strip footing is resting on the surface of a purely clayey soil deposit. If the width of the footing is doubled, the ultimate bearing capacity of the soil,

Becomes double

Becomes half

Becomes four times

Remains the same

Solution:

What is the correct formula for permittivity (φ) of geotextiles? Given: Kn = hydraulic conductivity for cross-plane flow, Kp = hydraulic conductivity for in-plane flow, t = thickness of the geotextile.

φ = t / Kn

φ = Kn / t

φ = t / Kp

φ = Kp / t

Solution:

A pile of 0.50 m diameter and a length of 10 m is embedded in a deposit of clay. The undrained strength parameters of the clay are cohesion = 60 kN/m² and the angle of friction 0°. The skin friction capacity (kN) of the pile for an adhesion factor of 0.6 is:

671

565

283

106

Solution:

Four columns of a building are to be located within a plot size of 10m x 10m. The expected load on each column is 4000 kN. Allowable bearing capacity of the soil deposit is 100 kN/m². The type of foundation best suited is

Isolated footing

Raft foundation

Pile foundation

Combined footing
