Coefficient of consolidation of a soil is affected by
A. compressibility
B. permeability
C. both compressibility and permeability
D. none of the above
Answer: Option C
Solution(By Examveda Team)
The coefficient of consolidation of a soil is affected by both compressibility and permeability.The coefficient of consolidation (Cv) is a measure used in soil mechanics to describe how fast a soil consolidates under load.
Compressibility influences how much volume change occurs in the soil when a load is applied.
Permeability determines the rate at which water can flow through the soil pores, affecting how quickly excess pore water pressure dissipates.
Therefore, the coefficient of consolidation is dependent on both these properties, making Option C the correct answer.
The angle of internal friction of a soil refers to:
A) The angle at which the soil fails under compressive stress
3
B) The angle at which the soil fails under tensile stress
C) The angle at which the soil grains are arranged relative to the horizontal
plane
D) The angle at which the soil can be tilted before it begins to slide.
