Q. In a settlement analysis, what does the term 'surcharge' refer to?
A.
The weight of the soil above the water table
B.
An additional load applied to the soil surface
C.
The weight of the foundation
D.
The weight of the soil below the water table
Solution
Surcharge refers to an additional load applied to the soil surface, which can increase the effective stress and lead to consolidation settlement.
Correct Answer:
B
— An additional load applied to the soil surface
Q. In a settlement analysis, which method is commonly used to estimate the time rate of consolidation?
A.
Terzaghi's theory
B.
Boussinesq's equation
C.
Mohr-Coulomb failure criterion
D.
Atterberg limits
Solution
Terzaghi's theory provides a framework for estimating the time rate of consolidation in saturated soils, taking into account the soil's permeability and compressibility.
Q. What is the primary factor affecting the consolidation settlement of saturated clay soils?
A.
Soil density
B.
Effective stress
C.
Permeability
D.
Plasticity index
Solution
Consolidation settlement in saturated clay soils is primarily influenced by permeability, as it determines the rate at which pore water can escape, allowing the soil to consolidate.
Q. What is the purpose of the coefficient of consolidation (Cv) in settlement analysis?
A.
To measure soil strength
B.
To determine the rate of settlement
C.
To assess soil permeability
D.
To evaluate soil plasticity
Solution
The coefficient of consolidation (Cv) is used to determine the rate at which consolidation occurs in saturated soils, reflecting how quickly pore water can dissipate.
Correct Answer:
B
— To determine the rate of settlement
Q. Which of the following factors does NOT directly influence the magnitude of primary consolidation settlement?
A.
Initial void ratio
B.
Applied load
C.
Soil type
D.
Soil color
Solution
Soil color does not influence the magnitude of primary consolidation settlement; it is determined by factors such as initial void ratio, applied load, and soil type.
Q. Which test is commonly used to determine the consolidation characteristics of soil?
A.
Unconfined compression test
B.
Oedometer test
C.
Triaxial test
D.
Direct shear test
Solution
The oedometer test is specifically designed to measure the consolidation characteristics of soil, including the compressibility and the coefficient of consolidation.
