1. Divide e-log p curve into linear segments
2. OC=Over consolidated (stiff response)
3. NC=Normally Consolidated (soft response)
4. OC and NC portions separated by ${\displaystyle \sigma _{p}^{,}}$
5. ${\displaystyle \sigma _{p}^{,}}$ = maximum value of stress hıstory
6. ${\displaystyle C_{r}}$=Recompression Index (slope of OC)
7. ${\displaystyle C_{C}}$=Compression Index (slope of NC)
8. ${\displaystyle C_{S}}$=Swell Index (slope of unload response)

A to B: ${\displaystyle C_{r}={\frac {\Delta e}{\Delta log(\sigma ^{'})}}}$ 0,01~${\displaystyle C_{r}}$ ~0,5

B to C: ${\displaystyle C_{C}={\frac {\Delta e}{\Delta log(\sigma ^{'})}}}$, 0,1 ~${\displaystyle C_{c}}$ ~2,6

${\displaystyle C_{C}={\frac {\Delta e}{\Delta log(\sigma ^{'})}}}$
