If you had a chain wall around the perimeter 36” down then it would encapsulate the interior soil and protect it from freezing effects. However; you would need to design the 8” slab with enough rebar to span the entire length assuming the soil below it shrinks and the slab is unsupported chain wall to chain wall.
