Particle flow interface simulation analysis test device and test method

The invention discloses a particle flow interface simulation analysis test device and a test method. The outer side of the bottom of a transparent annular loading cylinder is provided with a water inlet interface, a water outlet interface and a pressurization interface used for being connected with a pressurization device; arc-shaped pressure heads are arranged on the bottom surface of the annular loading plate, and a plurality of arc-shaped pressure heads are enclosed to form an annular loading piece capable of extending into the transparent annular loading cylinder in a sealing manner; the parallel light source is installed at the center of the upper surface of the vibration table through a component and used for emitting parallel light to the transparent annular loading cylinder. The camera device is arranged around the transparent annular loading cylinder and is used for acquiring a stress change image of the particle sample in the transparent annular loading cylinder; an annular track capable of being in
