Correlation between SPT and Passive Pressure
Correlation between SPT and Passive Pressure
(OP)
I am trying to find a correlation of SPT to passive pressure. I need to find the lateral capacity of a pile.
Appreciate any help.

RE: Correlation between SPT and Passive Pressure
If all you have is SPT N-values and you are in granular soils, you'd fine a correlation to friction angle and then use tan^2(45+phi/2) to get Kp. You'd then multiply Kp by Cp (phi/10) to get the ultimate passive pressure for the pile.
This is a pretty easy exercize. Now what's the lateral displacemnt under that horizontal load? That's where the body's buried. . .
