References for laterally loaded pole foundation
(OP)
Anyone know a good textbook reference for laterally loaded pole foundations? I am talking about a single pole with a single cast-in-place or driven steel pile below it. Pole height 20 to 40 feet high, subject to wind loads. No other unusual loads.
Have an old refernce that uses the friction angle of the soil to calculate a passive resistance of subgrade to pole forces. However, am searching for a technical book with more data. Any help appreciated.

I have that reference. It is very detailed on how to find the wind loads on tyhe pole, but less so on designing the foundations. I need to know more about the theoretical basis of the embedment nomograph (It doesn't make sense to me, frankly).
Are there any other texts out there that you know about that consider this topic?

Chapter 6 of this book presents procedures for the design of the laterally loaded pile(s)and has design examples.

1) Prof Bengt Broms has published formulas based on phi and c, and they give higher values than the Rankine (Bell) formulas for lateral passive pressure because they are specifically for piles. The pressures may be 1.5 x the Rankine values.
You can find a good description of these formulas in USA Corps Engineers Manual 'Bearing Capacity of Soils EM 1110-1-1905' which is available on the internet.
2) The Brinsch-Hansen formulas rely on more detailed knowledge of the soil properties and require more sophisticated analysis methods. You can find out more about this method if you do an internet search for the COM624 software package and for research done by Mokwa.

Pile Foundation Analysis & Design Poulos & Davis has a good section also.

The section of chapter 7 ("Retaining Structures and Foundations") is entitled "Lateral Stability of Poles."
