Side Friction in Limestone
Side Friction in Limestone
(OP)
Hi Everyone,
I've been trying to find the correct equations to use to determine side friction in Limestone in a Karstic Environment with a 30" dia. drilled shaft.
Initial tests show an RQD of 50% and qu = 5000 psi.
Any insight on the correct formulas to use would be great. I've referenced the FHWA manual and equations 13-18 and 13-19 seem to be what I'm looking for but I want to see what everyone's thoughts were.
Thanks!

The soil guys understand it much better than just some equations in a book that anyone can plug and chug. After all they do the borings so they have the info they need.
