Time rate of settlement
The coefficient of consolidation is the parameter used to describe the rate at which saturated clay or other soil undergoes consolidation, or compaction, when subjected to an increase in pressure. It is measure in square centimeters per second or square inches per minute.
Hence, the correct option is (A)

Coefficient of consolidation is a measure of the rate at which a soil consolidates under load. It is an important parameter for calculating the time rate of settlement in a soil.
Calculation of Time Rate of Settlement:
The time rate of settlement can be calculated using the following formula:
H = Cc * log10(t2/t1)
Where,
H = Settlement at time t2 – settlement at time t1
Cc = Coefficient of consolidation
t1 = Initial time
t2 = Final time
The coefficient of consolidation is used in this formula to calculate the time rate of settlement. It is a measure of the ability of a soil to transmit water under load. The higher the coefficient of consolidation, the faster the soil will settle under load.
Other Uses of Coefficient of Consolidation:
While the coefficient of consolidation is primarily used for calculating the time rate of settlement, it can also be used for other purposes, including:
- Determining the total settlement of a soil under load
- Calculating the preconsolidation pressure of a soil
- Estimating the stress in a soil under load
However, the coefficient of consolidation is most commonly used for calculating the time rate of settlement, as this is a critical factor in many construction projects.
