Permeability, unloading
F-d! I know wot you are saying...k=cv*gamma w*mv...true...but as I said in my last reply, both mv and cv are changing with stress...that's right if one can have mv and cv from a test it's possible to work out k based on this equation...well, after considering the difference between compression...- Piezoball

Permeability, unloading
Thanks for your reply f-d if you mean the equation which has mv and cv, it couldn't be used to directly calculate k since both mv and cv change with effective stress. it's relatively straight forward to calculate mv (let say based using MCC model)but cv is another parameter which should be...- Piezoball

Permeability, unloading
Hi fellows I appreciate it if anyone can refer me to a paper or text book talking about the change of soil permeability during unloading phase of consolidation test (Oedometer, Rowe cell or CRS test) I believe that permeability in any given soil is only related to the void ratio and stress...- Piezoball
