Total questions: 10
Worksheet time: 5mins
Which parameter is least affected by change in groundwater level?
A. Degree of saturation
B. Bulk unit weight
C. Apparent specific gravity
D. Void ratio
Which parameter is preferred in consolidation analysis and why?
Porosity, because it refers to total volume
Void ratio, because the volume of solids remains constant during compression
Degree of saturation, because it controls drainage
Water content, because it directly reflects settlement
Assertion (A): Void ratio can exceed unity, but porosity cannot. Reason (R): Void ratio is referenced to volume of solids, while porosity is referenced to total volume.
(A) Both A and R are true, and R correctly explains A
(B) Both A and R are true, but R does not explain A
(C) A is true, R is false
(D) A is false, R is true
Two soils have identical porosity. Which statement is necessarily correct?
Both soils have identical void ratio
Both soils have identical degree of saturation
Both soils have identical volume of voids
None of the above
Assertion (A): For a given soil, saturated unit weight is always greater than bulk unit weight.
Reason (R): Replacement of air by water increases mass without changing volume.
(A) Both A and R are true, and R correctly explains A
(B) Both A and R are true, but R does not explain A
(C) A is true, R is false
(D) A is false, R is true
Which of the following will decrease when a dry soil becomes fully saturated?
Air content
Degree of saturation
Bulk unit weight
Percentage air voids
A soil sample has high void ratio but low permeability. The most probable explanation is:
Soil is dense sand
Soil is gravel
Soil is clayey with micropores
Soil is partially saturated
A soil sample is partially saturated. If water is added slowly without allowing any volume change, which of the following parameters will certainly increase?
A. Void ratio (e)
B. Porosity (n)
C. Degree of saturation (S)
D. Volume of solids (Vs)
Which parameter is most sensitive to a rise in groundwater table?
Void ratio
Degree of saturation
Specific gravity of solids
Volume of solids
A soil is initially dry and later becomes fully saturated without any volume change. Which statement is correct?
A. Bulk unit weight remains unchanged
B. Dry unit weight increases
C. Saturated unit weight becomes equal to bulk unit weight
D. Degree of saturation changes from 0 to 100
