Description

technical field [0001] The invention relates to a triaxial rheological experiment device for tailings materials, which belongs to the technical field of mine geotechnical engineering. Background technique [0002] At present, soil mechanics is based on the following basic principles: 1) there is a proportional relationship between pressure and volume (i.e., pore) change, and between shear stress and shape change; 2) the compaction (consolidation) of soil over time is As a result of the movement of water along the pores in the soil, and this movement is subject to the law of infiltration; 3) The soil belonging to the dispersion medium not only has the cohesion between particles, but also has internal friction, these characteristics determine the anti-destructive strength of the soil . Based on the above principles and assumptions, it is possible to establish the linear deformation theory, seepage consolidation theory and limit equilibrium theory of soil. But at the same tim...

However, most of the currently developed rheometers are rheometers developed for "rocks", and there are very few rheometers specifically for tailings materials or fine-grained soil samples
