Solution:

What is the diameter of the bulb of an under-reamed pile?

2 times the diameter of the pile stem

2.5 times the diameter of the pile stem

1.5 times the diameter of the pile stem

1.7 times the diameter of the pile stem

Solution:

The net loading intensity at which the soil neither fails in shear nor there is excessive settlement detrimental to the structure is called

Net safe bearing capacity

Safe bearing capacity

Allowable bearing capacity

Bearing capacity

Solution:

The total, neutral and effective vertical stresses (in t/m²) at a depth of 5 m below the surface of a fully saturated soil deposit with a saturated density of 2 t/m³ would respectively be

5, 5 and 10

5, 10 and 5

10, 5 and 10

10, 5 and 5

Solution:

Net ultimate bearing capacity of a footing embedded in a clay stratum

Increases with depth of footing only

Increases with size of the footing only

Increases with depth and size of the footing

Is independent of depth and size of the footing

Solution:

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

106 kN

671 kN

565 kN

283 kN

Solution:

Which of the following statement(s) is/are not true for dynamic method of pile driving?

Suitable for both coarse-grained and fine-grained soils.

Not applicable for group action to find ultimate load.

Energy loss due to vibration and heat are not accounted for in the formula.

Not suitable for clays.

Solution:

The water table at a location is at the ground surface, and the saturated unit weight of the soil is 22 kN/m³. If due to heavy precipitation, the water level rises to 1.5 m above the ground level, the increase in the vertical effective stress (in kN/m²) at a point 1.5 m below the ground surface will be:
[Take γ_w = 10 kN/m³]
