Contact, study of rocks mechanics parameter in all cases and destructive characteristics can more scientifically and more effectively carry out engineering practice.
When carrying out the experiment of correlation properties of rock using electro-hydraulic servo rock three-axis tester, the measurement of deformation is extended using axial
It counts to complete, concretely comprise the following steps：Rock sample by coring, cutting, polishing processing and etc. into radius 50mm, the circle of height 100mm
Cylinder, according to the requirement of International Society of Rock Mechanics (ISRM), rock sample both ends irregularity degree is less than 0.05mm.Rock sample is fixed on bottom
On seat, outside suit chain type circumferential direction extensometer, Axial extensometer is divided into two parts, has certain thickness metal by two respectively
Annulus forms, and two annulus are respectively upper ring and a lower ring, and it is appropriate that upper ring and a lower ring answers severity to be placed on both sides above and below rock sample
The position of height, and the position of mounting hole in upper ring and a lower ring must correspond to, to ensure that metallic rod can be vertically inserted into
In the mounting hole of upper ring and a lower ring, correctness and reliability that Axial extensometer is related to result of the test can be accurately installed.
Nowadays many scholars carry out experiment of machanics using electro-hydraulic servo rock three-axis tester to rock, but to axial direction
It is still operated on the installation method of extensometer using man-hour manually hand-held.So bring the problem of several notable：(1) man-hour manually hand-held is axial
Extensometer, which carries out installing on rock sample, easily generates angle, height and the deviation of position, and authenticity is obtained so as to influence test data
And reliability.(2) manual operation takes longer, needs to take ruler on the other hand, adjusts the position of Axial extensometer on the other hand.(3) manually grasp
When making, if the installation of lower ring is not achieved level requirement, after upper ring installation when, can not just make the mounting hole of ring and the installation of lower ring
Hole is corresponding.(4) manual operation can not accurately ensure the setting height(from bottom) of Axial extensometer so that lower ring install it is excessively high or
The too low position for causing ring is away from the upper end of rock sample.It is greatly difficult that problem above brings experiment.Therefore, it is how accurate and square
Just it is the technical issues of being badly in need of solving in rock mechanics experiment to measure Axial extensometer desired height.
For the erecting device specifically for Axial extensometer in Rock Mechanics Test at present almost without.
