Analysis using the compression index

Equation for settlement when employing the compression index Cc of the i–th layer arises from the formula:

where: σor,i - vertical component of geostatic stress in the middle of ith layer
σz,i - vertical component of incremental stress (e.g. stress due to structure surcharge) inducing layer compression
eo - initial void ratio
hi - thickness of the ith layer
Cc,i - compression index in the ith layer
