Description
Technical field
A kind of information collecting device destroyed in real time based on rock of the present invention and method belong to Rock Mechanics Test technology neck
Domain.
Background technique
Rock mechanics research is one of the advanced subject of extensive concern in current rock mechanics field.Microscopic damage power
Research is from study of various damages on the meso-scales such as micro-crack, cavity in material form, distribution and its to develop special
Property.A kind of engineering material of the rock as complexity, there are initial fissures for inside, and under external force loading effect, initial fissure is able to
Extension, perforation, the interior strain energy stored of rock are just released in the form of elastic wave, and rock can be released in this change procedure
Acoustic emission signal is released, the acoustic emission probe that these acoustic emission signals can be attached to rock material surface monitors, through putting
Big device collects these acoustic emission signals by acoustic emission signal collector.
CT dynamic immediately scan test, seek coal petrography failure mechanism, purpose is to establish reasonable damage evolution equation and rock
Stone Damage constitutive relation provides scientific basis for the analysis of further progress rock mass strength and Deformation control.
But since rock interior is extremely complex, Original Cracks are constantly penetrated through during loading, development, the elasticity of generation
Wave largely discharges, and the acoustic emission signal supervened is difficult to capture, and can not be in the loaded state in real time by crackle and load
Establish connection；CT test is prohibitively expensive, is not suitable for the engineering project disaster real-time monitoring at scene；ROCK MECHANICS RESEARCH direction at present
In, study of rocks sample is also required to the research topic of rock fracture and damage and rock mass primary stress etc. and is ruptured in load
Property in the process.And the information for the rock sample that existing experimental rig can measure is very little, can not observe and analyze rock
Crack of the sample under point loading generates and expansion process, it is even more impossible to record and analyze data in real time on PC, data it is visual
Change degree is low.

It is middle to repeat to rub, it easily leads to and gets rusty, so that the real-time load of loading device error is occurred, influence experimental result.And acoustic emission probe
Setting be easy to produce confining pressure, to experiment generate large error；The third is the rock failure mechanism of rock that Institutes Of Technology Of Taiyuan develops
The experimental rig of characterization discloses in CN 104614251B file, and advantage can cooperate sound emission and CT scan equipment to use
And the influence of acoustic emission probe confining pressure is eliminated, but a disadvantage is that loading device is heavy, it is unfavorable for test specimen during CT scan
It places, and placement quantity of popping one's head in is few, is unfavorable for the positioning destroyed to test specimen, the rate of loading of loading device is smaller for certain strong
Spend biggish test specimen can not pressure break, for study unlike material the rock failure mechanism of rock produce great limitation, and experimental provision
Non-displacement test cell, in entirely load destructive process, rock interior crackle and load can not accurately establish each item number
According to connection in the loaded state.
