Yes, ANSYS Static Structural system includes an Elastic Foundation support where you can type in the stiffness.
Below is a 3 x 1 x 0.1 m slab of concrete. I added gravity and applied a pressure to the top face.

Here is the Longitudinal (X-axis) and Lateral (Z-axis) Normal stress in two views of the slab.
