Description
Technical field
The present invention relates to a kind of experimental provision for being applied to anchoring cyclic tension, dynamic load extension test, belong to mechanical analysis
And technical field of measurement and test.
Background technology
Bolt System has a wide range of applications in fields such as ground, side slope, coal mine support, hydraulic engineerings.In anchor pole
In terms of supporting quality and anchor pole performance evaluation, there are all kinds of technical regulation and a detection scheme, such as anchor pole static(al) pull-out test,
Anchoring quality Non-Destructive Testing scheme, cut resistance test, engineering site pull-out test etc..
Wherein carry out more to anchor pull-out test, the multi-purpose concrete of such experiment or steel pipe simulation in laboratory
Engineering rock mass.When used medium is concrete, anchor pole is screwed under rig drive in concrete test block or insertion is pre-
In the drilling first set, then space therebetween is filled up by Anchor Agent, and anchor rod body and cementing formed that drill anchor survey
Test system.When used medium is steel pipe, anchor pole is screwed in steel pipe under rig drive, and the two is then pre- by steel duct
The cementing formation anchor system of Anchor Agent put, or the two is bonded as integral fastening system using post-grouting means.
In the above-mentioned indoor anchor system testing scheme referred to, the anchor system of prepared shaping, which finally needs to carry out, to be broken
Bad property is tested.In traditional testing scheme, if the medium used is concrete, then destructive pull-out test can use
Anchor rod drawing tester, large-scale drawing (shearing) equipment can also be used；If using steel pipe, then related destructiveness
Pull-out test can use electro-hydraulic servo testing machine.For the latter, anchor pole-steel pipe anchor system is clamped on testing machine, clamping
End is respectively anchor pole end and steel pipe end.And the clamping that the clamping at steel pipe end uses specified scheme to remove to internal anchor pole more should
Power, avoid causing the situation of the single drawing of nearly anchor pole.By setting specific loading velocity and destructive test threshold value, anchor pole is final
Extracted from steel pipe, ultimate analysis failure mode, be fitted drawing force-displacement curve, draw the specific mechanical property of anchor system.
This testing scheme can be used to optimize the Anchorage Plan of particular form, or improve the mechanical property of anchor pole (anchoring material).
At home and abroad research institution is all widely used the anchoring test system of steel pipe-anchor pole combining form, such as moral
Research institute of Essen of state, the CIRSO research institutes of Australia, the China Coal Research Institute of China were all once examined using this scheme
The performance of test and appraisal valency Bolt System.But the limitation of experimental facilities is limited by, this scheme is only used for static(al) drawing survey
Examination, unable to do what one wishes is then seemed to circulation (dynamic load) load pull-out test.In ground field, the correlative study of (dynamic load) load is circulated
It is relatively conventional, but the research work generally carried out is both for rock sample under rock mass, such as uniaxial cycling (dynamic load) load
Hysteresis ring property, memory characteristic, rheological behavior etc., such as Hopkinson bar impact test.But this class testing is confined to more
Single shaft (three axles) compression verification, seldom it is related to stretching loop test.For support unit, related circulation (dynamic load) carries
Lotus test is just less.
For steel pipe-Bolt System mentioned above, carry out circulation (dynamic load) tensile load in laboratory
The faced technical barrier of test is very big.Main cause is：The Based on Electro-hydraulic Loading Servo System of existing list (three) shaft experiment machine is more
Designed for stretching or compression verification, in being applied with for circulation (dynamic load) load, different frequency, amplitude, endless form can be achieved
Compression circulation (dynamic load) load test.But certain bottleneck in terms of stretching then be present, although carrying out single extension test
Technology relative maturity, but high frequency circulation (dynamic load) extension test is but unable to reach and high frequency circulation (dynamic load) compression is surveyed
The same technical level of examination, more by the technology restriction of one or more aspects.
In ground field, the existing all kinds of engineering sites of circulation (dynamic load) disturbance frequency, such as in subway (railway) train it is reciprocal
Driving disturbance of neighbouring working face etc. in the frequent disturbance of big gun pick, engineering excavation in operation, coal mine roadway.Although to rock
The circulation dynamic loading mechanical characteristic of (soil) has carried out many test analysis work, but for support unit (especially
Anchor pole) research done of the mechanical characteristic analysis in the case where circulating dynamic loading not enough, the work of related research test analysis has very much
It is necessary.
