Concrete piles

(OP)
Does anyone know of a treatise (user friendly) to estimate lateral resistance of cast-in-place concrete piles in sand or clay

RE: Concrete piles

User friendly (classical) theories of earth pressure (Coulomb and Rankine) don't work well with single piles, partly because a pile is a small, three-dimensional object - rather than a two-dimensional wall. Also because active and passive earth pressures are not mobilized until complete failure.

However there are controversial ways that can be used, the easiest is a "Prescriptive Solution". See paragraph 7.2.2 of this State of Indiana DOT document (page 49 of the 75 page .pdf download) for both a warning and an answer to your question

RE: Concrete piles

Try the USACE.
They have a pretty good one for the lateral pile resistance.
Used mathcad to calculate the springs and the results from SAP matched exactly those from MPILE.
