Overconsolidation Index of Secondary Compression
The overconsolidation index of secondary compression depends on laboratory measurements (e.g. one-dimensional consolidation) and is proportional to the logarithm of time and slope of virgin consolidation line providing the preconsolidation pressure was not exceeded:
where: | Cαr | - | overconsolidation index of secondary compression |
ε | - | deformation of a soil layer | |
t1 | - | initial time of a period of monitoring (measured from the onset of consolidation) | |
t2 | - | final time of a period of monitoring |
