Cantilever Sheet Pile Seeing Surcharge Plus Strip Load
Cantilever Sheet Pile Seeing Surcharge Plus Strip Load
(OP)
Hey guys,
I'm really trying to wrap my brain around this. I have a Cantilevered Sheet Pile that is holding back 13ft of earth. I'm assuming soil density is homogeneous throughout and I have granular soil. I have a surcharge load and a Cooper E80 Strip load. I know that the 100psf surcharge is going to act uniformly along the sheet. I know the strip footing pressure can be found using Boussinesq Equation, but I read I can take 0.8 of the worst case pressure (for a given length and depth away from the sheet) and apply a uniform pressure along the sheet as well.
First, can anyone confirm the 0.8 assumption?
Second, does anyone have an example problem showing a cantilevered sheet pile in granular soil with a surcharge load? I'm interested to see how the pressure diagram changes when the surcharge is applied.
Any help is appreciated. I can post the 4 pages of calcs I have if needed.
Thanks,

As for E80 loading, most railroads don't allow a Cantilever sheet pile wall within the zone of influence of the tracks for any reason. I suggest you check with your cleint and/or the railroad before putting much effort into the design.

I would apply the uniform lateral load down to the toe of the sheet. It is additive to the pressures acting on the "pushing" side, so you will have to extend your toe for the statics to work out.

(February 1974) - This could help you in understanding one of the processes. You can find a copy of CalTrans Trenching and Shoring Manual Revision 12 at vulcanhammer.net, this also might help. Happy reading and learning!
