Void Ratio vs Strain on Consolidation Test

Void Ratio vs Strain on Consolidation Test

(OP)
Consolidation test graphs of stain vs load look identicle to void ratio vs load.  The void ratio values decrease as the load incease, conversely the stain increases as the load increase.  If one recieve graphs showing strain vs load can they easily be converted to void ratio vs load?

What other info do I need to convert from one to the other.

RE: Void Ratio vs Strain on Consolidation Test

Slope of the strain-log p' plot gives the recompression ratio (Cr/(1+eo)) if not yet to the preconsolidation pressure and the compression ratio (Cc/(1+eo)) on the virgin consolidation line.  I happen to like the strain-log p' plot as I don't need to determine the eo value.

You can easily relate vertical strain to void ratio by using a phase diagram.  

Vertical Strain = (Delta e)/(1+e0)

BigH actually gives this above, but less bluntly.  Also, as BigH states, the strain-log p' plots are actually preferred by many, since they simplify some settlement calculations.

(Apologies to BigH for basically restating his post)

It'll cost you a brew if we ever meet!!
