In Enercalc-Pole Embedment in soil
What does Allow passive and Max passive means? I know basics but need elaboration.

" Allowable Passive Pressure

The allowable lateral force the soil can withstand. This value will be increased per foot of vertical embedment depth. For example, at 4'-0" below the surface allowable lateral pressure entry of 150 psf/ft would be able to resist 150 * 4 = 600 psf.


· Regardless of maximum value entered in the next entry the allowable pressure will not be raised when the depth of embedment is below 12'-0". "

" Max Passive

Maximum allowable passive pressure regardless of depth, and load duration factor to be used to increase the allowable pressures. Per code "

Does this help or do you need more explanation? I'm happy to help if I can.
