Hi all,
In Plaxis, the term initial void ratio is defined as eo or the void ratio represent the OBP of the soil? I think it should be eo as consolidation settlement equation relating Cc and Cr depends on the eo, therfore Is any way to calculate the eo of the soil?
When we take the sample from the site it becomes as OC => void ratio changes, then how can we use that value (from laboratory experiment) to input to the soil that is on-site? Is any corrections or correlations available?
What is the most accurate correlation of the compression and re-compression/swelling index of the soil which is mostly adopted in the design when there is no data available?
Thanks.

Dear Nitha,
Unfortunately there isn't any reliable correlation. The only way is to conduct odometer tests to get the corresponding data. If you still can access a consolidation test data, then you need to use the given correlations with caution and sound engineering judgement.
