Question
What is coefficient of soil consolidation? What is its unit?
Solution
The coefficient of soil consolidation is a parameter used in geotechnical engineering to quantify the rate at which a particular soil type will compress under load, specifically due to expulsion of water from the pores between soil grains. It is a measure of how quickly a soil will consolidate.
The coefficient of soil consolidation is typically denoted as Cv and is calculated using the formula:
Cv = (mv * k) / gw
where:
- mv is the coefficient of volume compressibility,
- k is the coefficient of permeability, and
- gw is the unit weight of water.
The unit of the coefficient of soil consolidation is typically expressed in m²/s (square meters per second) in the International System of Units (SI).
