1D Consolidation Test: Lab Procedures

[@jimdanial5735]

woah finally we get to see Professor Kitch in person!!! thank u for all these years!

[@ahasanulhaquehashib7773]

oh! I can finally see how you look! Professor Kitch, thank you so much for the work you put in and the knowledge you freely share. I know it comes from years of hard work. You have taken me through numerous exams successfully without fail. You are a modern day hero! Kind regards Hasib

Holy Crap! I can finally see how you look! Lol Professor Kitch, thank you so much for the work you put in and the knowledge you freely share. I know it comes from years of hard work. You have taken me through numerous exams successfully without fail. You are a modern day hero! Kind regards Eugene

[@matinjalalimoghadam1549]

Highly appreciate your time and experience you freely shared with people around the globe. As a PhD student it was really influential for my studies. Tnq indeed Prof. Kitch.

[@TheAncientColossus]

Thank you for keeping me motivated to become a Geotechnical engineer in times like this Professor! I hope I can be as knowledgeable in Geotechnical Engineering one day!

[@DongjinPark-so2iq]

Thanks so much Prof. Kitch. You have been saving many people from complexity of geomechanics. Hoping you are healthy and fine amid covid 19 From south korea

Is it not necessary to perform the unloading-loading cycle in order to calculate the swell index and recompression coefficient?

[@altviooltje]

Do you use also Taylor and the Bjerrum and the isotachen methode to do the calculations for al parameters?

[@willliamkitch2967]

Yes, you can use those methods. For my intro geotech class I teach just the Casagrande method, because I think it’s the most intuitive. In practice I like to use the Taylor method as well because it allows you to project ahead where Casagrande’s method allows you to find t-100 only by looking back in time. If you need the secondary compression index, you need to use Casagrade’s method. I don’t use Bjerrum’s isochrone theory. It’s not common in practice in the US.

God bless you our dear professor

[@farhanshaher3032]

Can you please explain why mostly we get degree of saturation of the final more than the initial and some times we get degree of saturation more than 100% ?? Thanks

[@youwilllaugh3136]

There are no such things as more than 100% degree of saturation

[@JamesCaseEndercase]

There is if you assume or find your specific gravity incorrectly. 😂 ​@@youwilllaugh3136

[@JamesCaseEndercase]

If you get a higher than original degree of saturation after consolidation and pressure release then your sample wasn't saturated in situ and/or your sample dried after sampling. If the sample starts at 100% saturation it can't go any higher than that but it "can" still swell if you test it at a lower pressure than in situ with available pore water of a similar salinity. 100% saturation in situ isn't always 100% at 1 atm. That's one reason why the decree of saturation calculated a 1 atm lab unit weight isn't really in situ. @farhanshaher3032

great professor

It's amazing, thank you
