Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
Embodiment: a kind of Triaxial tester being applicable to soft rock, its structure as Figure 1-3, including:
Base 22, base 22 is fixedly connected with support 1；Described support 1 is hollow structure, support 1 have side plate and with
Side plate fixes the cross top board of connection, the mid portion of cross top board lower surface and fixing company of Z axis stress loading mechanism 2
Connect.
Side plate is divided into upper and lower two parts, and lower part is fixing with base 22 to be connected, and upper part is fixing with cross top board to be connected,
Fix with stress loading mechanism between upper part with lower part and be connected.
Stress loading mechanism includes two, respectively ShiXZhou stress loading mechanism 4 and Y-axis stress loading mechanism 3, described X-axis
Stress loading mechanism 4 is positioned at above Y-axis stress loading mechanism 3.
The structure of two stress loading mechanisms is identical, and it is mutually perpendicular to.Arbitrary stress loading mechanism all includes shell 8,
Shell 8 is internal has base plate 18, base plate 18 is provided with two bearing blocks 13, is provided with positive and negative silk leading screw between two bearings seat 13
16, this positive and negative silk leading screw 16 is driven motor 19 to drive, and the both sides of positive and negative silk leading screw 16 are slide rail 15.
Positive silk and anti-silk part on positive and negative silk leading screw 16, be separately installed with the first slide block 14 and the second slide block 17, and two is sliding
Being respectively provided with the screw suitable with described positive silk or anti-silk inside block, two slide blocks are all guided by slide rail 15.By driving motor 19
Driving, then two slide blocks can be carried out relatively close or are located remotely from each other motion.
Meanwhile, each slide block is all connected with a connecting plate 5, and the top of connecting plate 5 is fixing with increased pressure board 7 to be connected.Difference
Being, connecting plate 5 length in Y-axis stress loading mechanism 3 is relatively big, and the upper and lower surface that the most just can make four increased pressure boards 7 is equal
It is in same level.
The structure of four increased pressure boards 7, size are the most identical with material, this makes it possible to further improve load on sample
The evenness of stress.Meanwhile, each increased pressure board 7 is internal is mounted on pressure transducer 20, in order to by sample 9 pressure experienced
Signal is transferred to information acquisition system 21.
Selecting as one, described can be oil cylinder in Z axis stress loading mechanism 2, or other have planar structure
The mechanism of loading surface, simultaneously, it is also desirable to a pressure transducer 20 is installed in Z axis stress loading mechanism 2.
From the point of view of being easy to control, described driving motor 19 can be chosen as motor or servomotor, so
Just can further improve measuring accuracy, it is simple to control the stroke of increased pressure board 7, come the change by increased pressure board 7 displacement, sample
9 subjected to stress change and crush the mechanical characteristic of information summary research sample 9.
For the sample of unlike material, the flatness on its surface is not quite similar.Feel relieved for the ease of sample, this device
In also in X-axis stress loading mechanism 4, be fixedly connected with a sample holder 11, there is ball-type groove, in groove in sample holder 11
Being provided with place kick 12, place kick 12 and sample holder 11 form universal ball structure.Place kick simultaneously 12 is connected with support bar 10,
Strut 10 is fixing with locating piece 6 to be connected, and locating piece 6 is used for placing sample.
After have employed above-mentioned location structure, sample 9 just can be placed on locating piece 6, and locating piece 6 can freely turn
Dynamic, it becomes possible to during pressure-loaded, to make sample 9 automatic capturing center, improve the accuracy of sample precision.
With reference to shown in Fig. 5, as more preferably selecting, the orthographic projection of described locating piece 6 be positioned at sample holder 11 orthographic projection it
In.So can make sample that certain deflection occurs in the case of being not affected by external force, but be affected by action of gravity will not be from fixed
Landing on the block 6 of position.
It is important to note that during testing, it is necessary to assure the orthographic projection of sample is than sample holder 11
Orthographic projection is bigger, so can ensure that increased pressure board 7 can add to be pressed on sample 9 rather than add and be pressed on sample holder 11.
Simultaneously in order to ensure the precision of triaxial test, can carry out friction-reducing measures with increased pressure board 7, its effect is to reduce sample
And the friction between increased pressure board.I.e. sticking the thin film of folder lubricant between increased pressure board 7 and sample face, lubricant can use butter
Mixture with machine oil.
The process utilizing this device to carry out testing is as follows:
A, sample 9 is positioned on locating piece 6；
B, the piston rod of oil cylinder is made to extend, until contacting with sample end face, it is ensured that sample upper and lower surface is close to level；
C, make the driving motor 19 of X-axis and Y-axis stress loading mechanism rotate, then four increased pressure boards 7 synchronize to lean on to sample 9
Closely, until increased pressure board 7 is fitted with sample 9；
D, continue to make two to drive electric machine rotations, and make the piston rod of oil cylinder persistently extend, it is achieved three axles of sample 9 are added
Pressure；During pressurization, record increased pressure board 7 displacement and sample 9 STRESS VARIATION.
Information acquisition system 21 gathers the force value in 3 directions, the multiple side of sample and the deformation values of end face simultaneously, and remembers
The record time.And the figure formed between each data and each data can be browsed on software interface at any time.It is attached on increased pressure board
Pressure transducer by the displacement of rock and pressure changing information as electronic signals, is transferred to computer, passes through corresponding software
Display rock pressure experienced value size in real time.
Because driving motor can be chosen as servomotor, and servomotor and computer can forming closed loop control, because of
This can calculate the displacement of increased pressure board by the rotation number of turns of servomotor, and the displacement synchronous of increased pressure board is recorded in software
In, and then consider the mechanical characteristic of soft rock.
After have employed said structure, this device can carry out multi-scale rock and the single shaft of concrete, twin shaft test and
Rock mass and the medium-sized direct shear test of structural plane, it is also possible to carry out the tests such as the long-term rheology of true triaxial of middle size rock, shear rheology.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
Multiple amendment to embodiment will be apparent from for those skilled in the art, as defined herein typically
Principle can realize without departing from the spirit or scope of the present invention in other embodiments, is not described in detail
The part presented with partial enlargement, for prior art, does not repeats at this.Therefore, the present invention is not intended to be limited to herein
