The admixture of coarser particles like sand or silt to clay causes
Decrease in both liquid limit and
plasticity index
The water content in a soil sample when it continues to loose weight without loosing the volume, is called
Shrinkage limit
A decrease in water content results in a reduction of the volume of soil in:
A. Liquid state
B. Plastic state
C. Semi-solid state
Negative skin friction on piles
A. Is caused due to relative
settlement of the soil
B. Is caused in soft clays
C. Decreases the pile capacity
Volume change in saturated soils caused by the expulsion of pore water from loading?
Primary Consolidation
A process by which water-saturated soil sediment temporarily loss strength and acts as a fluid.
Liquefaction
One of the following foundation
conditions does not affect the bearing capacity of the supporting soil.
Load imposed onto the soil
If the ground water table in a soil formation rises as resulting of flooding, the bearing capacity of the soil:
Rise of water table above the ground surface causes:
Equal increase in pore water pressure and total stress
The shear strength of a soil:
Decreases with decrease in normal stress
Effective stress on soil:
Decreases both voids ratio and
permeability
The coefficient of compressibility of soil, is the ratio of:
Strain to stress
An index used to identify the swelling potential of clay soils is called
Activity
The property of a soil which permits water to percolate through it
Permeability
Which of the following methods is best suited for determination of permeability of coarse grained soils?
Constant head method
