Formulas for calculating stressunder concrete slab resting on elastic or viscous subgrade/soil

[soil1999]

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 loading) is applied.
Or formulas to calculate vertical stress in soil under a conceret rigid pavement slab.
(Elastic slab resting on viscous or solid elastic foundations)
Thanks

Any of the pavement design texts will show you this or you can use the PCA design procedure or the AASHTO design procedure. See Yoder and Witczak,
