Foundation Settlement for Embankments
Foundation Settlement for Embankments
(OP)
I am designing a waste rockfill (10m high) on compact sand and gravelly sand foundation (Average corrected SPT = 24). Looking for a methodology to measure the settlement under the foundation and then check that the membrane would not be stretched excessivley under differential movements. I would appreciate your feedback.

I correct my question that I am looking a methodoloy to calculate settlement and then choose the appropriate membrane. Sorry for the wrong use of word "measure"

CGPR is the "Center for Geotechnical Practice and Research at Virginia Tech. The thrust of this publication pertains to the actual settlement of the rock fill itself rather than the foundation soils supporting the rock fill.
If you are dealing with N-values of 25 or so, I'd use elastic theory to evaluatate the settlemet of the foundation soils. Now, what's the best method to evaluate elastic modulus? Right now you just have N-values. You could use a dilatometer. You could just take 7N (or 11N) and return a value of 175 to 275 tsf. Then it's just a matter of determining the change in stress from the embankment and integrating the stress change and dividing out the modulus.
At least I think I got that right. . .
