Shoring with backfill
Shoring with backfill
(OP)
I am proposingto use sloped backfill to provide lateral reinforcement to a concrete basement wall . The building is being demolished but portions of the basement wall have to remain in place as the floor above is removed. Has anyone done anything similar. Also, any methods of placement and compaction suggestions are appreciated.





RE: Shoring with backfill
I am concerned that you will not have the room to place the soil in a controlled manner. I think you should not plan on having any compaction.
Per standard practice, you will need to calculate the passive resistance taking into account the slope of the material (Coulomb Kp). You should probably also discount the passive contribution from the top foot or two of the soil against the wall (similar to sheet pile wall design).
If you can achieve compaction, there was a good thread recently that dicussed the effect of compaction on lateral wall loads.
