　　This case utilizes electrical resistance tomography and 3D printing technology to physically simulate and experimentally monitor the three-dimensional geometric shape of rotary sprinkler irrigation piles. Firstly, a three-dimensional printing technology was used to construct a model of carbon crystal conductive reinforcement material similar to rotary jet grouting piles. Secondly, a resistance tomography system was used to reconstruct and model the solidified rotary jet grouting piles. Finally, a small reinforced sample was constructed using powder three-dimensional printing technology to study the solid geometry and mechanical properties. Through experimental research, physical experimental data on the three-dimensional reinforcement morphology and mechanical characteristics of rotary jet grouting piles under indoor working conditions were obtained. The application of electrical resistance tomography and three-dimensional printing technology in geotechnical reinforcement research was explored, providing preliminary validation data for subsequent mathematical modeling and numerical simulation analysis of three-dimensional reinforcement morphology.
