Based on the mirror image method for the spherical cavity expansion with nonaxisymmetric displacement boundary
assuming that the soil as the linear elastic constitutive model
the soil compaction displacement field is obtained through the modifications of surface boundary stress and inclination boundary stress
the soil compaction displacement field could consider different boundary angles
different distances from spherical cavity position to the boundary
etc. The results indicate that the influence of boundary inclination angle on the soil compaction displacement would be gradually smaller with the reduce of inclination angle; and the larger distance from spherical cavity position to the boundary
has the smaller influence on the soil squeezing displacement. The results provide some reference for similar engineering design and parameter settings.
