Description
Technical field
The present invention relates to a kind of triaxial rheology experimental provision of tailings material, belong to Geotechnical Engineering field, mine.
Background technology
Current, soil mechanics be take following ultimate principle as basis: 1) between pressure and volume (being hole) variation and relation in direct ratio between shear stress and change of shape; 2) soil densification (fixed) is in time the result of moving along native mesoporosity due to water, and this motion submits to seepage law; 3) belong to the soil of dispersion medium, not only have intergranular cohesive strength, and have internal friction, these characteristics have determined native resistance of failure.Based on above these principles and hypothesis, just may set up native linear deformation theory, infiltration consolidation theory and limit equilibrium theory.But meanwhile, these principles and hypothesis are idealized by soil characteristics to a certain extent.In fact, the proterties of soil is very complicated when loading, the time effect of soil distortion for example, and as strength decreased under creep, lax and load long term etc., in other words, the growth that soil can be in time and stress, the strain regime of change itself.And another feature of soil is the non-linear of stress and strain relation, the especially distortion of time to time change.In addition, also should be taken into account native fundamental characteristics, the internal friction that is it not only occurs when ultimate limit state, and also occurred before ultimate limit state, thereby the feature to development of deformation exerts an influence, this feature of soil is because its resistance to compression is different with shearing strength formed, has caused causing that such as shear stress cubic deformation (cutting swollen) and equal confined pressure power cause detrusion etc. some abnormal phenomenon like this.Therefore, under load action, the actual proterties of soil and desirable concept have significant difference.Although the idealized of native characteristic is feasible to actual computation in some cases, if ignore native These characteristics, can cause result of calculation and field condition grave fault; The result of long-term creep has many such examples: as can be caused the distortion of works; The instantaneous strength adopting in calculating rather than long-term strength can cause side slope and retaining wall to destroy; Non-linear owing to not considering, can cause the calculated value of sedimentation and actual value to have very big difference.Considered native deformation characteristics, just likely more accurately studied native actual characteristic, thereby can make theoretical close to native actual conditions.
China is a mining powers, and annual ore dressing produces approximately 300,000,000 tons of mine tailings, and except fraction is as filling in mine or comprehensive utilization, the overwhelming majority will be stored up with the form of tailing dam.Yet, because China is in the scientific research less investment aspect tailing dam, lagging of scientific research, scientific and technological level is low, cause the serious accidents such as tailing dam dam break occur again and again, as September 8 in 2008 there is especially big tailing dam dam-break accident in the Xin Ta of ， Xiangfen in Shanxi mining industry company limited, 270 people are dead, and this time accident has caused extremely severe social influence and environmental hazard.By Administration of Work Safety Supervision, be called " the tailing dam accident of whole world maximum up to now ", according to statistics, 14 tailing dam security incidents only just occurred for 2007.Yet, a long-term process of the landslide of Tailings Dam of Mine and dam break process (quantitative change-qualitative change), this process is a process of mine tailing generation rheology.The importance of therefore, carrying out the triaxial rheology experiment of tailings material is not sayed and pre-.However, the rheological experiment instrument majority of current exploitation is all for " rock " and the rheological experiment instrument of exploitation, and special considerably less for the flow graph of tailings material or particulate soil sample.

The 6th step: if draining is tested, open the valve of pore water drainpipe 28; Not draining is tested, and closes the valve of pore water drainpipe 28.Then in pressuring shaft 2, increase the quantity of the I 3 that heavily sticks together, until reach requirement of experiment, then continue this mitriform state (if need to change experiment parameter in experimentation, by designed requirement of experiment, complete), to meet the duration of designed rheological experiment, and record weight, the displacement of pressuring shaft 2 and the pressure gauge reading of pore water piezometric tube 32 applying until test end.
The 7th step: after experiment finishes, take off heavily stick together I 3 and the II 6 that heavily sticks together, and open the valve of drainpipe 27, get rid of the water in pressurization cavity volume 18.Finally unload other member of this experimental provision, next group experiment of position is prepared.
The invention has the beneficial effects as follows:
(1) can carry out the triaxial rheology experiment of the tailings material under " draining " and " not draining " condition.
(2) experimental period based on rheological experiment is longer, thus rely on the quantity that increases the II that heavily sticks together to carry out compressed liquid (generally adopting water), thus soil sample is applied to confined pressure (being σ 3 values).This not only saves the plenty of time, manpower and power cost, and can also obtain stable and lasting confined pressure.
(3) by increasing the I that heavily sticks together of axial loading device, experiment soil sample is applied to axle pressure, also can obtain lasting and stable axle pressure.
(4) this invention is by the triaxial rheology experiment under electromagnetic shaker energy failure under earthquake action (i.e. moving triaxial rheology experiment).
(5) in experimentation, can the real time measure soil sample mesoporosity hydraulic pressure variation, apply the parameters such as size of confined pressure.
(6) parameter (as adjusted the size etc. of soil sample pore water pressure, confined pressure and xial feed) of rheological experiment can be in experimentation, changed in real time, thereby native rheological characteristics can be more furtherd investigate.
(7) can complete the rheological experiment that constant confining pressure and constant shaft are depressed, also can carry out the rheological experiment under non-constant confined pressure and non-constant axial compression simultaneously
(8) can, in the situation that saving a large amount of manpower and financial resources, obtain and comparatively stablize lasting rheological parameter.
The present invention can simulate under geological process, carries out the rheological experiment under constant confining pressure, axial compression and non-constant confined pressure, non-constant axial compression; Meanwhile, can carry out the triaxial rheology experiment of tailings material under " draining " and " not draining " condition.In addition, experimental period based on rheological experiment is longer, apparatus of the present invention are that the quantity that relies on increase heavily to stick together applies different confined pressures and axial compression, the pressure that the pressure ratio propulsion system (by Electric Machine Control) that obtain like this obtain is " safety ", " stablizing ", " lastingly " more, and can save the plenty of time, manpower and financial resources.Therefore, apparatus of the present invention are not only saved a large amount of human and material resources and financial resources, have also greatly improved reliability and the accuracy of the tailings material rheological parameter of surveying.Thereby for the stability study of Tailings Dam of Mine dam body provides more reliable rheological parameter.
