Anchored Soldier Beam Wall Example

[BadgerPE]

Does anyone know of a good design example/reference for an anchored (single and multiple) soldier beam wall? I have been tasked with updating a previous design (never built) to the current LRFD standards required by my state's DOT. The original engineer on this wall is no longer with the company and I don't fully agree with his methodology for the wall design so I am looking for some documentation to back up my reservations.

I have reviewed AASHTO and FHWA documentation, but am left desiring a little more information on the calculation process since this is not a space that I work in daily.

I believe one of the NAVFAC manualS cover this topic.

Maybe not what you can use, but recently I did a Google search for a similar situation and many many examples of these walls came up.

Perhaps your DOT has some design guidelines. For example, Here is CA DOT design manuals:

Sorry for the late response, but thank you to all for the assistance. As I got more familiar with the terminology, I found several good resources online.

AASHTO provides a load factor of 1.35 on the apparent earth pressure (AEP) for the active pressure on anchored walls, but does not provide a reduction factor for the passive pressure resistance. Should there be a reduction factor applied to the passive pressure to meet LRFD requirements? I am leaning towards applying a 0.9 reduction factor on the passive to arrive at a FS of 1.5 which is inline with all of the references that I have read on this topic (pre-LRFD of course).

BadgerPE, the FHWA site has also lots of information for retaining structures:

https://www.fhwa.dot.gov/engineering/geotech/search_result.cfm

This appears to be a good manual but because is dated on 1999 there is not LRFD consideration there:
