Load under an Embankment

[learning2geotech]

The highest influence factor for a load under embankment is only 0.5. So let's say at depth z=1 foot below the bottom of the embankment at its crest, the load is reduced by 50%! That doesn't seem right to me. For comparison, the influence factor is 0.9 within approx. 0.3B below a footing. See attached screenshot Influence Factor Chart-Infinitively Long Embankment from NAVFAC, which shows influence factor ranges from 0 to 0.50.

The figure is for one-half of an embankment, you'll need to to double the influence value if the right half is identical.
