Testing device capable of realizing dynamic acquisition of freeze-thaw surface and internal images of soil body

The utility model discloses a test device capable of realizing dynamic acquisition of freeze-thaw surface and internal images of a soil body, which comprises a soil sample tank, a high-resolution camera and a data acquisition unit, and further comprises a CT (Computed Tomography) scanner and a track, one end of the track extends into the CT scanner, a working platform is arranged on the track in a sliding manner, and the working platform is connected with the data acquisition unit. A soil sample tank is fixedly arranged above one end, close to the CT scanner, of the working platform, an annular track arranged along the circumference of the soil sample tank is fixed on the working platform, and the high-resolution camera is arranged on the annular track in a sliding mode. The CT scanner can be used for dynamically collecting internal images in the soil body freeze-thaw process, and the defect that a traditional soil body freeze-thaw image collecting and testing device can only independently collect freeze-thaw
