Strip Load surcharge on Sheet pile wall with sloped backfill
Strip Load surcharge on Sheet pile wall with sloped backfill
(OP)
I am doing analysis on a sheet pile headwall for a CMP culvert under a railroad. I have been looking but have been able to figure out how to determine the lateral pressure from a strip load surcharge when the backfill has a 1:2 slope. I orginally just used the Bousinesq formula, but because of the slope and distance from the centerline of track, it seems that this may be much too conservative.
I was looking at this thread thread255-150849: Surcharge Pressure on Retaining Walls , the last post mentions a reference from Poland, and I really wish I knew the exact source so that I could include it in my calculations, at least for why the surcharge won't need to be included. Does anybody know of a publication that refers to how to calculate the "Clear distance to surcharge"?

What do you think? Do you agree with not considering the surcharge after a certain distance from the load?

Poisson's ratio is more of a player than the actual surcharge magnitude itself.

V:H & H:V both in use. There is no problem to distinguish the correct from sketch (unless you left out the symbol and numerical values for slope), when writing, try 2H:1V, or 1V:2H for clarity. Make sense?

Sorry, I don't have the name of the publication. I xeroxed these sheets 25 years ago from a book I couldn't purchase. The book was brought here (US) from Poland by an engineer that I worked with. Didn't occur to me to write down the name of the book (duh). I've never seen solutions like these anywhere else. For more discussion, and the derivation to the formulas posted in the other thread, see thread507-240214: Loading Behind Retaining Wall due to Existing Commercial Builds. Also, Here's a PDF of the solution to a surcharge at the top of a sloped fill, case No. 10.
