Abstract: To reveal the characteristics and differences of reconstructed soil bulk density in different profiles of the reclaimed land, the southern dump, western dump, expanded western dump and internal dump of the Antaibao open pit mine in Pingshuo were taken as the research objects, the differences of reconstructed soil bulk density were analyzed, and the relationship between dielectric constant and reconstructed soil bulk density was established by using the methods of ring knife sampling weighing, ground penetrating radar detection, variance analysis, and fitting analysis. The results show that:(1) The reconstructed soil bulk density had significant differences in different dumps and different depths of the same profile. (2) The differences of reconstructed soil bulk density in different dumps was qualitatively analyzed based on the large amplitude signal on the ground penetrating radar images. (3) The reconstructed soil bulk density (y) increased linearly with the change of the dielectric constant (x) when soil volumetric water content was less than 15%, and the fitting function was y=0.054 3x+1.019 2, R²=0.508 3, P=0.001. Ground penetrating radar has the popularization and application value in detecting reconstructed soil bulk density and the development of the non-destructive quality testing of land reclamation.
