Q. What is the effect of water table on the bearing capacity of a foundation?
A.
Increases bearing capacity
B.
Decreases bearing capacity
C.
No effect
D.
Depends on soil type
Solution
The presence of a water table can decrease the effective stress in the soil, leading to a reduction in bearing capacity due to buoyancy effects and increased pore water pressure.
Q. What is the primary cause of settlement in saturated clay soils?
A.
Consolidation due to applied loads
B.
Soil erosion
C.
Soil compaction
D.
Frost heave
Solution
Settlement in saturated clay soils primarily occurs due to consolidation, which is the process of volume reduction in soil due to the expulsion of water from the pores under applied loads.
Correct Answer:
A
— Consolidation due to applied loads
Q. What is the primary cause of settlement in saturated cohesive soils?
A.
Consolidation due to applied loads
B.
Shrinkage due to drying
C.
Erosion due to water flow
D.
Frost heave
Solution
Settlement in saturated cohesive soils primarily occurs due to consolidation, which is the process of volume reduction in soil due to the expulsion of water from the pores under applied loads.
Correct Answer:
A
— Consolidation due to applied loads
Q. What is the primary cause of settlement in saturated soils?
A.
Soil compaction
B.
Consolidation due to pore water pressure dissipation
C.
Soil erosion
D.
Soil expansion
Solution
Settlement in saturated soils primarily occurs due to consolidation, which is the process of pore water pressure dissipating over time, leading to a reduction in volume.
Correct Answer:
B
— Consolidation due to pore water pressure dissipation
Q. What is the primary factor affecting the bearing capacity of soil in a case study involving shallow foundations?
A.
Soil type
B.
Water table level
C.
Foundation depth
D.
All of the above
Solution
The bearing capacity of soil is influenced by soil type, water table level, and foundation depth, making all of these factors critical in case studies.
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.
