Based on the simulation results of the finite element software, setting up an experimental platform, and the echo signals reflected from the hole interface are collected on the concrete test block, and the positioning imaging is realized through the time inversion model. According to the simulation imaging research, in this paper, the peak-time contrast imaging method will be used to analyze and compare the displacement field, stress field, and energy field respectively. Finally, damage imaging will be performed through the energy field.
