Prressure Treated Wood Retaining Wall

Prressure Treated Wood Retaining Wall

Prressure Treated Wood Retaining Wall

(OP)
I have a retaining wall that requires a redesign.  The contractor originally constructed the wall without a design.  It was constructed of 6x6 pressure treated lumber in (approximately) 8 feet sections.  Every so often a dead man was placed using 6x6's also.  The inadequacy was mainly due to poor construction of the wall as well as non-compacted soil conditions.

Now that it collapsed, the contractor realizes the worth of an engineer.  Since I am asked to take responsibility for the retaining wall, it needs to be done correctly.  I am familiar with the idea of this design, but would like to have a design guide to reference.

Thanks in advance.

Hey boo1, thanks for the reply.  I am having problems finding the information at that link.  If you could elaborate, I would greatly appreciate it.  Although, I think we are on the same page, let me note that the wall is a freestanding retaining wall.  Other than fixity at the base (or not - depending on the design), the only restraint is due to deadmen.  This is not a house (i.e. there is no floor at the top to provide support).

Thanks,

Andy

RE: Prressure Treated Wood Retaining Wall

Andy - I have an old US Steel Catalog (in Adobe Acrobat format) that has design information on retaining walls with and without tieback systems. If you need it quickly, will be happy to e-mail it to you. Another option - the information is available on an L.B. Foster Co. piling catalog (on CD). You can request the CD at www.lbfoster.com

RE: Prressure Treated Wood Retaining Wall

Are you planning a soldier pile and lagging wall, or cribbing?  How tall is it?  Location?  Soil conditions?  Any site restraints?
