Q. What is the effect of loading rate on the settlement of clay soils?
A.
Faster loading rates increase settlement
B.
Faster loading rates decrease settlement
C.
Loading rate has no effect on settlement
D.
Settlement is only affected by soil type
Solution
Faster loading rates can increase settlement in clay soils because they do not have enough time to dissipate pore water pressure, leading to greater immediate settlement.
Correct Answer:
A
— Faster loading rates increase settlement
Q. What is the purpose of a settlement plate in field monitoring?
A.
To measure soil permeability
B.
To monitor lateral earth pressures
C.
To measure vertical displacement over time
D.
To assess soil shear strength
Solution
Settlement plates are used in field monitoring to measure vertical displacement over time, allowing engineers to assess the amount of settlement occurring.
Correct Answer:
C
— To measure vertical displacement over time
Q. What is the significance of the coefficient of consolidation (Cv) in settlement analysis?
A.
It indicates the soil's shear strength
B.
It measures the rate of pore water pressure dissipation
C.
It determines the soil's permeability
D.
It assesses the soil's compressibility
Solution
The coefficient of consolidation (Cv) is significant in settlement analysis as it measures the rate at which pore water pressure dissipates, influencing the rate of consolidation and settlement.
Correct Answer:
B
— It measures the rate of pore water pressure dissipation
Q. Which type of foundation is most susceptible to differential settlement?
A.
Shallow foundation
B.
Deep foundation
C.
Mat foundation
D.
Pile foundation
Solution
Shallow foundations are more susceptible to differential settlement due to variations in soil properties and loading conditions across the foundation area.
