Description

A Triaxial Rheological Experimental Device for Tailings Materials

technical field

The invention relates to a triaxial rheological experiment device for tailings materials, which belongs to the technical field of mine geotechnical engineering.

Background technique

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 time, these principles and assumptions idealize the properties of soil to a certain extent. In fact, the properties of soil are very complicated when loading, such as the time effect of soil deformation, such as creep, relaxation, and strength reduction under long-term load, etc. In other words, soil can change its own properties with time. Stress and strain state. Yet another characteristic of soil is the non-linearity of the stress-strain relationship, especially the time-dependent deformation. In addition, the basic characteristics of the soil should be taken into account, that is, its internal friction occurs not only at the limit state, but also before the limit state, thereby affecting the characteristics of the deformation development. This characteristic of the soil is due to its The difference in compressive and shear strengths leads to some deformities such as volume deformation (dilatation) caused by shear stress and shear deformation caused by confining pressure. Therefore, the actual behavior of the soil under load differs significantly from the ideal concept. Although idealization of soil properties is feasible for practical calculations in some cases, ignoring the above characteristics of soil will lead to calculation results that are seriously inconsistent with field conditions; there are many such examples: results such as long-term creep can lead to Deformation of structures; instantaneous strength instead of long-term strength used in calculations can lead to failure of slopes and retaining walls; non-linearity is not considered, resulting in settlement calculations that differ significantly from actual values. Considering the deformation characteristics of the soil, it is possible to study the actual characteristics of the soil more accurately, so that the theory can be close to the actual situation of the soil.

China is a big mining country, and about 300 million tons of tailings are produced by ore dressing every year. Except for a small part as mine filling or comprehensive utilization, most of them are stored in the form of tailings dams. However, due to the low investment in scientific research on tailings dams in my country, the lag in scientific research, and the low level of science and technology, major safety accidents such as tailings dam failures have occurred frequently. For example, on September 8, 2008, Xinta Mining Co., Ltd., Xiangfen County, Shanxi The company suffered a huge tailings dam collapse accident, and 270 people died. This accident caused extremely bad social impact and environmental disasters. It is called "the largest tailings dam accident in the world so far" by the State Administration of Work Safety. According to statistics, there were 14 tailings dam safety accidents in 2007 alone. However, the landslide and dam break process of mine tailings dam is a long-term process (quantitative change-qualitative change), and this process is a process of tailings rheology. Therefore, the importance of carrying out triaxial rheological experiments on tailings materials is self-evident. Nevertheless, 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.

(5) During the experiment, parameters such as the change of pore water pressure in the soil sample and the magnitude of the applied confining pressure can be measured in real time.

(6) The parameters of the rheological experiment can be changed in real time during the experiment (such as adjusting the pore water pressure of the soil sample, the confining pressure and the size of the axial load, etc.), so that the rheological characteristics of the soil can be studied in depth.

(7) Rheological experiments under constant confining pressure and constant axial pressure can be completed, and rheological experiments under unconstant confining pressure and unconstant axial pressure can also be carried out
