Background technology

Current, soil mechanics is based on following elements: direct proportionality between 1) pressure and volume (i.e. hole) change and between shear stress and change of shape; 2) soil densification (consolidation) is in time the result because water moves along native mesoporosity, 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 determine the resistance of failure of soil.Just may set up based on these principles above and hypothesis that the linear deformation of soil is theoretical, Seep-Solidifying is theoretical and limit equilibrium theory.But meanwhile, these principles and hypothesis to a certain extent that soil characteristics is idealized.In fact, the proterties of soil is very complicated when loading, the time effect of such as soil distortion, and as intensity reduction under creep, lax and load long term etc., in other words, soil can stress, the strain regime of growth in time and 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 the fundamental characteristics of soil, namely its internal friction not only occurs when ultimate limit state, and also occurred before ultimate limit state, thus the feature of development of deformation is had an impact, this feature of soil is because its resistance to compression is different with shearing strength formed, and result in such as shear stress and causes cubic deformation (cutting swollen) and equal confined pressure power to cause detrusion etc. some abnormal phenomenon like this.Therefore, native under load action actual proterties and desirable concept have significant difference.Although the idealized of native characteristic is feasible to actual computation in some cases, if ignore the These characteristics of soil, then result of calculation and field condition grave fault can be caused; There are many such examples: the result as long-term creep can cause the distortion of works; The instantaneous strength adopted in calculating instead of long-term strength can cause side slope and retaining wall to destroy; Non-linear owing to not considering, the calculated value of sedimentation and actual value can be caused to have very big difference.Consider the deformation characteristics of soil, just likely more accurately study the actual characteristic of soil, thus the theoretical actual conditions close to soil can be made.

China is a mining powers, and annual ore dressing produces mine tailing about 300,000,000 tons, and except fraction is as except filling in mine or comprehensive utilization, the overwhelming majority will be stored up with the form of tailing dam.But, because the science research input of China in tailing dam is few, 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 on September 8th, 2008, there is especially big tailing dam dam-break accident in Xin Ta mining industry company limited of Xiangfen in Shanxi, 270 people are dead, and this time accident causes extremely severe social influence and environmental hazard.Be called " the tailing dam accident that the whole world is maximum up to now " by Administration of Work Safety Supervision, according to statistics, only within 2007, just there occurs 14 tailing dam security incidents.But the landslide of Tailings Dam of Mine and the long-term process (quantitative change-qualitative change) of dam break process one, this process is the process that mine tailing stream occurs becomes.Therefore, the importance of 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 the rheological experiment instrument of the exploitation for " rock ", and special considerably less for the flow graph of tailings material or particulate soil sample.
