Description
technical field [0001] The invention belongs to the technical field of geotechnical engineering tests, in particular to a test device for generating, transmitting and monitoring temperature-controlled dry air for geotechnical tests. Background technique [0002] The earth-rock dam has the advantages of strong adaptability to the terrain, local materials, and simple construction technology, and is one of the common dam types in dam construction. Since the 1980s, the construction of earth-rock dams in China has developed rapidly. During the actual construction and operation of the project, the dam body and core wall are under complex environmental conditions, and there are coupling effects of temperature, humidity and stress conditions. Changes in temperature and humidity have certain effects on the strength and deformation of dam materials. Therefore, under the premise of accurately controlling temperature and humidity changes, it is of great significance for the safe operat...
