Expansive soil toe and heel pressures
Expansive soil toe and heel pressures
(OP)
My foundation is on expansive soil and I must provide 800psf DL pressure min and 3000 psf maximum.
When I am designing a cantilevered retaining wall foundation, do I need to try and keep the heel pressure above 800psf and toe below 3000psf.

RE: Expansive soil toe and heel pressures
The discussion with my geotech now concerns whether or not the expansive soil pressure
should be considered in the overturning calculation. Seem to me that it should be included, but
she is saying it is some type of live load. My feeling is if the heel pressure falls below 800, it is
not correct. I think of soil pressure in any direction as a dead load. Any thoughts?
