Sheet pile for scour protection
Sheet pile for scour protection
(OP)
We're trying to resolve the forces acting on a sheet pile wall. If you look at the attached pdf we believe the effective width of the concrete arch and the soil wedge of select structural fill on top of the arch can be analyzed as a line load distributed through the 8' footing. We're not so sure the 16' of indigenous fill should be analyzed as surcharge acting on the wall. If anyone has any suggestions it'll be welcome. Thanks.

When you say that the 16' should be looked at as a block do you mean a 16'x16' block of soil? Some people at the office didn't feel the 16' surcharge acts on the sheeting directly but on the frame itself and puts a resultant force above the sheet pile (transferred from the side of the frame to the footing to the sheet pile)

If the earth surcharge and the traffic surcharge are beyond the failure plane, then a qKa rectangular surcharge should not apply. However, this could be a hard sell to the highway department. If you use a Boussinesq surcharge analysis, the effect may not be too bad because of the distance behind the sheeting.
