6:40 Why is this equation used instead of the coefficient of volume compressibility, mv (m sub v)? Would mv be a general case? While 2.3*sig z is a special case of changing soil conditions? And if so, how do we solve this?
This is the only textbook that computes the coefficient of consolidation in this way. Every other textbook uses the coefficient of compressibility to compute the coefficient of consolidation. Which is the outdated method?
Well, if you haven't found the answer yet... Mv assumes linear relationship between void ratio and effective stress which isn't the case. But when you plot change in e vs log of effective the curve flattens out hence Cc method is more accurate.
Love your video respectable sir, i hope you're always in good health so you can teach us more about soil world 👍
And there was evening and there was morning. And i am going to pass my Geotech exam.
"Buckle your seatbelts and sharpen your pencils; here we go" -The very thing I am gonna say when my exam starts. Thank You, sir! Great explanation!!!
Excellent presentation
love from nepal
Thank you very much
Excellent video. Good banter too :p

You are so cool!
