technical field [0001] The invention relates to an experimental testing instrument for geotechnical materials in geotechnical engineering, in particular to an intelligent geotechnical shear rheometer. Background technique [0002] Under the influence of external force and engineering environment, most rock and soil materials have time-related mechanical behaviors. If they are subject to changes in the stress field, temperature field, or seepage field at the same time, or they interact with each other, it will lead to changes in the rheological deformation path of the soil. Changes and deformations are accelerated, and engineering disasters, such as mudslides, landslides and landslides, will eventually occur, which will bring great harm to human production and life.

[0002] Under the influence of external force and engineering environment, most rock and soil materials have time-related mechanical behaviors. If they are subject to changes in the stress field, temperature field, or seepage field at the same time, or they interact with each other, it will lead to changes in the rheological deformation path of the soil. Changes and deformations are accelerated, and engineering disasters, such as mudslides, landslides and landslides, will eventually occur, which will bring great harm to human production and life. It is a very important engineering application research content in the field of mechanics. However, the current geotechnical shearing instruments have the characteristics of complicated operation steps, low test accuracy, and difficult data acquisition and processing. Therefore, an intelligent geotechnical shear test instrument is needed to meet the current testing work of a large number of geotechnical materials

[0003] After searching the literature of the prior art, it is found that the patent authorization number CN 101498650B discloses a five-link rock uniaxial rheometer, which is only used for rock uniaxial rheological testing, because there is no shear box, and the rock and soil shear The rheology cannot be tested, and the rheology test under two-way load cannot be measured. Since the power is provided by the motor, it cannot provide a constant load value for the long-term soil rheology test, and its data software cannot provide automatic real-time data processing and early warning functions. Therefore, a geotechnical shear rheometer with bidirectional load action, high test accuracy and intelligence is needed
