Abstract

The invention discloses a freezing-thawing centrifugal model box in a freezing-thawing deformation centrifugal simulation system. The freezing-thawing centrifugal model box comprises a heat exchange system and a model box body, wherein the heat exchange system covers an opening of the model box body and consists of a sealed box body and multiple semiconductor devices arranged in the sealed box body; the multiple semiconductor devices are arrayed on a heat exchange base plate at intervals and are connected with the heat exchange base plate; a plurality of sensor mounting holes are formed in the sealed box body in clearances of the multiple semiconductor devices and consist of upper holes formed in a top heat exchange cover and lower holes corresponding to the heat exchange base plate; a sensor mounting sleeve is arranged in each sensor mounting hole; a through hole is formed in each sensor mounting sleeve; the sizes of the through holes are slightly larger than the sizes of the lower holes in the heat exchange base plate; the upper ends of the sensor mounting sleeves penetrate through the upper holes and are fixed on the top heat exchange cover; the bottom ends of the sensor mounting sleeves are fixed on the upper surface of the heat exchange base plate around the lower holes. The freezing-thawing centrifugal model box is reasonable in structure and convenient for displacement sensor mounting, and can realize flexible extending amount adjustment of sensors and meet a requirement on depths of different soil models.

Description

technical field [0001] The invention relates to a freeze-thaw deformation centrifugal model test system, in particular to a freeze-thaw centrifugal model box in the freeze-thaw deformation centrifugal simulation system. Background technique [0002] Centrifugal simulation test technology has been widely used and developed rapidly in different industries such as national defense, medical treatment, geotechnical research and so on. Centrifugal test equipment is an important link to realize this technology. [0003] The freeze-thaw centrifugal model test system is a centrifugal test equipment used to study the frost heaving and thawing phenomena of related buildings or facilities in permafrost areas due to large temperature changes. This kind of test equipment is rarely developed and applied in China, and it is currently in its infancy. The freeze-thaw centrifugal model test system is mainly composed of freeze-thaw model box, circulating cooling water system and control syste...
