Spherical cavity expansion-induced soil squeezing effect adjacent to slope

Assuming that the soil is the linear elastic constitutive model for the cavity expansion and pile-sinking induced soil squeezing effect adjacent to slope, with the pile of penetration for simulating spherical cavity expansion process, the soil compaction displacement field are presented considering different boundary angles based on the mirror image method. The results indicate that the influence of inclination boundary on the soil compaction displacement becomes smaller with the decrease of inclination angle. The results will provide some reference value for engineering design.
