https://communities.bentley.com/products/geotech-analysis/f/forum/217632/initial-void-ratio-einit-and-cc-cr-valueHi 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 calculateen-USTelligent Community 12https://communities.bentley.com/thread/664785?ContentTypeID=1Thu, 05 Aug 2021 09:51:23 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:f7f5a922-cea6-45f7-8f36-a96284984c98Nitharshan<p>Thanks&nbsp;</p><div style="clear:both;"></div>https://communities.bentley.com/thread/664630?ContentTypeID=1Wed, 04 Aug 2021 19:35:07 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:ebfe0b04-3926-4f86-af4a-3ada5309ff80Jamal Hassan[quote userid="1084806" url="~/products/geotech-analysis/f/plaxis-soilvision-forum/217632/initial-void-ratio-einit-and-cc-cr-value"]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?&nbsp;[/quote] <p>Dear Nitha,</p> <p>Unfortunately there isn&#39;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.&nbsp;</p><div style="clear:both;"></div>
