A new feature that was released with PDisp 19.4 was the consolidation settlement analysis (instantaneous, primary and secondary). This feature is particularly useful for engineers investigating the behaviour of clay and organic soils and when working with raft foundations.
Application Specialist, Zeena Farook, hosted a webinar presenting this new feature and the theory behind it. Watch the webinar here.
What does PDisp do with its consolidation settlement?
PDisp 19.4 calculates instantaneous settlement in the drained and undrained soils, it will then calculate its primarily consolidation in the undrained soils. There are two options for the user;
- mv Method (linear)
- Cc Method (non-linear) – considers normally consolidated soils and overconsolidated soils
PDisp can also then calculate the secondary consolidation in the undrained soil.
