Q. What is the purpose of a Standard Penetration Test (SPT) in site investigation?
A.
To measure the moisture content of soil
B.
To determine the density and strength of soil
C.
To assess the permeability of soil
D.
To classify soil types
Solution
The Standard Penetration Test (SPT) is used to determine the density and strength of soil by measuring the number of blows required to drive a sampler into the ground.
Correct Answer:
B
— To determine the density and strength of soil
Q. What is the significance of the consolidation settlement in foundation design?
A.
It indicates the soil's ability to support loads
B.
It measures the soil's shear strength
C.
It predicts the long-term settlement of structures
D.
It assesses the soil's permeability
Solution
Consolidation settlement is significant in foundation design as it predicts the long-term settlement of structures due to the expulsion of water from soil voids.
Correct Answer:
C
— It predicts the long-term settlement of structures
