Roller Loading as surcharge to bulkhead
Roller Loading as surcharge to bulkhead
(OP)
I am designing a sheet pile wall on a creek and I have one problem. I am not sure what loading to apply as a surcharge on the surface behind the wall. I believe that the construction loading will be the highest loads this site will see but I am not sure how to apply the load from a vibratory roller or large dozer since there seems to be no standard for such a loading. So I was wondering if anybody had any ideas on how to estimate something like this. The equipment will be a Cat Low Ground Pressure D-6 Blade and a Dynapac CA-25 vibratory roller. Any comments would be helpful. Thank you.

Where the wall is designed for active pressures, not at-rest, we found that keeping walk-behind compactors 18", preferably 24", away (using sand backfill) that they do not do this cumulative presume increase effect.
The uncompacted zone hangs up with the "silo effect", not causing surface settlement later.
