I know this subject is touched on in

Alexander, R.M.  1985.  Mechanics of posture and gait of some large 
     dinosaurs.  Zoological Journal of the Linnean Society 83:1-25.

I can't remember which direction the calculations went, mass from 
footprints or ground pressure from estimated mass, but I do seem to 
remember Alexander concluding that sauropod feet might have exerted a 
ground pressure similar to that produced by the treads of a main 
battle tank.
