retaining wall w/ piles
currently i am working on a retaining wall, but due to the loading and limitied land, i am looking into designing a retaining wall, with a concrete beam instead of the footing which connects to piles.  i have been looking at different references and i am gathering information.  but i have not been able to find a reference that shows the design process for this concrete structure (retaining wall, with a concrete beam instead of the footing, and piles for the lateral loads).  
i would really appreciate if you guys can advice me of a reference i can look into to help me out with this design.
thanks
i do not have any references at hand other than a design drawing showing such a set-up and it is "heavy" in piles. basically, the vertical loads will be taken by the piles and the horizontal pressures will have to be taken by the moments at the beam-pile interface.  in other words, you will have large moments resulting in lateral loading on your piles.  one way to alleviate this is to use tie-backs to deadmen taken back beyond your active zone.  offsetting the horizontal loading on the wall by horizontally loaded deadmen would mitigate the bending moments on your piles.
peck, hanson and thornburn has an excellent example.  we do the wall with less heel so the toe compressive pile is not as heavily loaded and the other row is typically half in tension.  i draw a triangle with the compression vertical leg and the horizontal load base and the hypotenuse gives me load and the angle is the angle i install the pile.
have you considered a geoweb system or a mechanically stabilized slope?
they have a much lower concentrated load.
actually, this wall is for flood control purposes, so its going to retain approximately 15 feet of water.  
i obtained a copy of peck, hanson and thornbur.  the isolated column footing on pile on section 23.6 of page 379 has a footing instead of a beam.  also the pile-supported retaining walls example on section 26.8 of page 428 also has a footing instead of a concrete beam.
do you guys think this is something i can work from, or do you guys have any recommendations of another reference that has more inline with what i am working with.
thanks
can you clarify?  i figured you meant pile supported cantilevered wall where the base is a grade beam on piles instead of a footing on grade.  if you are worried about no backfill, i did a flood wall design and used the weight of water on the heel.  the authority had misgivings and i don't recall if it stayed in the final design,  but i think the piled retaining wall example is what you need.
yes, i am designing pile supported cantilever wall where the the base is a grade beam instead of a footing on grade.   so can i use the example on page 436 "foundation design for pile-supported retaining wall" even though this example has a footing instead of a concrete beam?  is this the example you are talking about?
thanks
have you looked at'double wall" concrete wall? we used one for a storm water detention pond. total of 35 feet wall height. very small footing. holds back the earth
richard a. cornelius, p.e.
i've designed counterfort walls using piers or augered piles instead of cantilevered retaining walls with footings.  have you considered that?
