MSE Retaining Wall system design (redi-rock)
MSE Retaining Wall system design (redi-rock)
(OP)
I am working on designing a two tier redi-rock retaining wall system. The tiers are 15 feet in height and would require long geogrids. I was wondering if I use a special foundation system say a concrete footing on caissons would that help with sliding and hence reduce the length of geogrid.

Don't forget to have the global stability of the wall system checked by someone who understands slope stability.

FHWA NHI 00-043 gives the following advice for tiered walls:
"For the lower wall consider the upper wall as a surcharge in computing bearing pressures. In lieu of a conventional external sliding stability computation perform a slope stability analysis with failure circles exiting at the base. A minimum factor of safety of 1.5 is generally warranted."
Make sure the person doing the slope stability knows what they are doing. Good luck.
