Reduced bin pressure using geosynthetic reinforcement
Reduced bin pressure using geosynthetic reinforcement
(OP)
We are looking to reduce lateral earth pressures (i.e., silo or bin pressures) resulting from backfill between a permanent soil nail wall and a multi-level building. Backfill dimensions are approximately 4 feet horizontal between the soil nail wall and structure and up to a max. height of approximately 22 feet. We have considered geofoam and other lightweight backfill, but want to consider a less expensive option. Does anybody have experience or references for reinforcing the backfill with geogrid or geotextile? And how to calculate what a reduction the reinforcement would have on the bin pressure? Backfill could be angular gravel.

The designer will have to come up with a method of tying the soil nail wall and the MSE together - this is dependent on the termination detail of the nail and the denisty of nails in the structure.
