Analysis Using the Compression Index
Equation for settlement when employing the compression index Cc of the ith 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 | |
e0 | - | initial void ratio | |
hi | - | thickness of the ith layer | |
Cc,i | - | compression index in the ith layer |
