Consolidated H / initial Height = change in e /( 1+initial e)
Inversely proportional
BCz ultimate consolidation settlement means change in height i.e)∆H.if the initial void ratio (e) is high then expulsion of watere from soil will be more in turns it requires less change height i.e )it has to do less wrk (∆H) to expel the water.....
But I think whereas for compressibility the increase in e also increases the compressible character of soil.
How?
