Abstract
A visible test system includes a test chamber system, a heating system, a pressure control system, and a high-energy accelerator CT detection system configured to scan and detect the seepage and migration of magnetic fluid in fractures in a sample. The test chamber system includes a pressure chamber and a sample encapsulation device immersed in hydraulic oil arranged inside the pressure chamber. The heating system includes a magnetic fluid heating device, a resistance wire heating device and a temperature detection device. The magnetic fluid heating device includes a magnetic fluid loading pump configured to supply the magnetic fluid injected into the sample encapsulation device and an alternating magnetic field control device configured to provide an alternating magnetic field for heating the magnetic fluid. The resistance wire heating device is configured to heat the hydraulic oil. The present invention makes the fracture connectivity change during rock mass fracture visible.
