concrete piles
does anyone know of a treatise (user friendly) to estimate lateral resistance of cast-in-place concrete piles in sand or clay
find a job or post a job opening
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
i use broms' theory which was included in a superseded version of the australian piling code.
by googling i found this web reference;
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.
