A vacuum chamber structure of an ultra-high gravity geotechnical centrifuge device, comprising: a cylindrical shell, a convex head, a bottom head, a lower bearing sealing cover, and a vacuum pressure-bearing chamber formed by sealing a top cylindrical cylinder and an upper sealing plate with sealing rings; wherein a high-speed rotor system is enclosed in the vacuum pressure-bearing chamber, and a cylindrical cooling device is installed between an internal side of the cylindrical shell and the high-speed rotor system. An annular cooling device is provided directly above the hanging baskets on both sides of the centrifuge arm. A vibration isolation expansion joint is arranged at the intersection of the high-speed rotor system and the cylindrical cylinder, which isolates the vibration of the main engine from the vacuum chamber and greatly reduces the vibration.
