Stratum measurement simulation apparatus

The utility model provides a stratum measurement simulation apparatus, comprising an original stratum, a hollow loose backfill layer, a macadam backfill layer and a dry saw-dust layer, wherein the original stratum a cuboid area in a normal stratum. A cuboid gap is arranged on a right-upper portion of the original stratum. The dry saw-dust layer is mounted on a bottom of the gap. The hollow loose backfill layer and the macadam backfill layer which are used for filling the gap are disposed on the dry saw-dust layer in parallel in the gap. A material of the hollow loose backfill layer is loose soil and a material of the macadam backfill layer is macadam. When the stratum measurement simulation apparatus is measured by a geological radar, effects of each stratum on ARMA spectrum density can be analyzed to obtain and accuracy when the geological radar observes geology is raised.
