Is anyone familiar with an engineering program that aids in the design of piles subjected to lateral loads embedded in two different types of  substrates?  I have a retaining wall on a hill side supported on piles and grade beams.  The site is covered with a layer of fill.  Bellow the fill is a layer of marine terrace and bellow the marine terrace is bedrock.  Both the marine terrace and bedrock are suitable to provide lateral support for the piles (based on the recommendation of the soils engineer).  Using the "flag pole embedment" equation commonly used to design piles subjected to lateral loads, the required depth of embedment for the pile is deeper than the layer of marine terrace, that being the case, it seems advantages to consider both materials in resisting the lateral loads the pile is subjected to (Because of the depth of the marine terrace, it doesn't make a whole lot of sense to ignore it).  However, the "flag pole" equation does not lend itself directly to situations when two different types of materials are considered.

Thank you
