Stress distribution
Stress distribution
(OP)
Can any one guide me to analytical formulas calculating vertical stress distribution in soil underlined by a conceret slab over which a surface load (like traffic) is applied.
Or formulas to calculate vertical stress in soil under a rigid pavement slab
Thanks

A very good paper, with practical instructions to build up a spreadsheet, is the following:

RE: Stress distribution
It does depend on the reinforcement and thickness of the concrete slab/pavement structure (your DOT may not account for that though).
I'm studying the horizontl component of this question right now. Somethings are not as easy as they seem. . .

Thanks for your reply. Basically rigid pavement books provide the bending moments, stresses, and shear at different locations in the slab itself.
What I am interested in is the Vertical stress distribution in the soil under a concrete square or strip raft loaded with distributed square load or point/concentrated load on the surface.
I have looked in AASHTO but was not able to find any related formula , charts, or guidelines on this matter.
Thank you
