Device and method for testing floating stability of barrel type foundation model

The invention discloses a device and a method for testing the floating stability of a barrel type foundation model. The device for testing the floating stability of the bucket type foundation model comprises the bucket type foundation model, a water tank for floating of the bucket type foundation model, a negative pressure adjusting system for adjusting the internal pressure of the bucket type foundation model, and a deviation correcting system arranged on the bucket type foundation model and used for preventing the bucket type foundation model from inclining. According to the test device and the test method for the floating stability of the barrel-type foundation model, the stability of the barrel-type foundation model in the sinking process is enhanced through the design of the deviation rectifying system, the sinking inclination angle of the barrel body is strictly controlled, the sinking stability and controllability of the barrel-type foundation model are remarkably improved, and the stability of the bar
