Schmertmann and Hartmann Equation for settlement

[Calif]

Can this equation be used for saturated sands with a base loaded base of 150 feet and a sand layer only 5 feet deep?

The resisant virtues of the structure that we seek depend on their form; it is through their form that they are stable, not because of an awkward accumulation of material. There is nothing more noble and elegant from an intellectual viewpoint than this: to resist through form. Eladio Dieste

If you have a loaded area that's 150 ft square, you should consider the elastic response of more than just that one sand layer. Just to be clear: Is the sand layer 5-ft thick or is the top of the sand layer 5 ft below the slab and then really thick?

I would likely use a modulus-based settlement evaluation along the lines of the Schmertman method, recognizing that modulus values increase with confining stress and the seat of settlement is not likely to be much deeper than 100 ft or so. . . . .

It has about 60 feet of clay underneath. I am just wondering if this equation can be used with sand which is saturated because the water table is at the ground surface.
