Hi Peter,
you can use v.to.rast to create a raster surface from the vector
surface (as Maskus suggested) and then use r.to.rast3elev to fill the
upper volume and the lower volume of a new voxel map with different
values (upper = 1, lower = 2). Then use r3.mapcalc to perform
operations on the upper or lower volume (r3.mapcalc "lower_volume =
if(myvolume == 2, 1, null())").

Best regards
Soeren
