I have actually just found it! It is called Absi's formula. Check out the link if you are interested.http://etd.lsu.edu/docs/available/etd-07122007-165444/unrestricted/Rohit_Thesis.pdf
Hello,
I recently came across a formula giving an average value of the coefficient of consolidation from representative values for different layers. Unfortunately I cannot remember where I saw this. Does anyone know something about this formula?
Thanks for the references.
To dicksewerrat: I think that hoop stress is indeed, in most cases, a tensile stress due to internal pressure, but the formula to get it still works if the pressure is external (in which case it becomes compressive). See the remarks in the link on my first post
This might more belong to the structure section, but I guess it's quite common in geotechnics.
I want to calculate the stresses induced in a thin-walled buried pipe. I am using the usual formula for the hoop stress (see the link): sigma=P*R/t
Also I'm using the vertical total stress for P, as...
CRS-tests have been performed at 3 different depths, and the clay appears to be underconsolidated (the OCR ratio is around 0.8). It might appear strange after so many years but the amount of fill that was placed is about 7m (another problem in this case in the lack of reliable information about...
I'm actually trying to assess how much the soil (soft clay) has consolidated so far. The problem is that the overload (fill) was placed some 60 years ago and the only values that I have are from last year. I wonder if using the now-value of Cv to calculate T and U (with Terzaghi's theory) makes...
Hello everybody,
Does anyone know anything about the variation of the coefficient of consolidation (Cv) with time (i.e. as consolidation is going on)?
My goal is to obtain a rough estimate of Cv when the consolidation process began, knowing its present value.
Has any study been performed on...
