The utility model discloses a freeze-thawing centrifugal model box in a freeze-thawing deformation centrifugal simulation system. The freeze-thawing centrifugal model box in the freeze-thawing deformation centrifugal simulation system comprises a heat exchange system and a model box, wherein the heat exchange system covers a box opening of the model box and comprises a sealing box body and a plurality of semiconductor parts arranged in the sealing box body; the plurality of semiconductor parts are arranged on a heat exchange base plate at intervals and connected with the heat exchange base plate; a plurality of sensor mounting holes are formed in the sealing box body at the interval of the plurality of semiconductor parts; each sensor mounting hole comprises an upper hole in a heat exchange top cover and a lower hole corresponding to the heat exchange base plate; a sensor mounting sleeve is arranged in each sensor mounting hole; a through hole is formed in the sensor mounting sleeve; the size of the through hole is a little greater than that of the lower hole in the heat exchange base plate; the upper end of the sensor mounting sleeve passes through the upper hole and is fixed to the heat exchange top cover; the bottom end of the sensor mounting sleeve is fixed on the upper surface of the heat exchange base plate at the periphery of the lower hole. The freeze-thawing centrifugal model box in the freeze-thawing deformation simulation system is reasonable in structure and capable of facilitating mounting of a displacement sensor, flexibly adjusting elongation of the sensor and meeting the depth requirements of different soil models.
