Rock dynamic and static true/normal triaxial shear rheology thmc multi-field coupling test device
A technology of triaxial shearing and testing equipment, which is applied in the direction of testing material strength by applying stable shear force, measuring equipment, and testing material strength by applying repetitive force/pulsating force, which can solve the problem of inability to load stress and inaccurate test results. Accurate, can not guarantee all contact with the side of the sample and other issues

Embodiment 1
[0128] Example 1: Conventional Triaxial Compression Test
[0129] In this embodiment, a conventional triaxial compression test is carried out on a rock sample, and the specific test operation steps are as follows:
[0130] Step 1: Lift the confining pressure chamber 5, put the circular rock sample 34 (the conventional triaxial is a cylindrical sample, and the lateral pressure is loaded by hydraulic pressure) on the sample base block 29, and place the sample Put the sample heat-shrinkable sleeve 39 on the outside, place the upper part of the sample pad 31 on the upper part, install the sample upper-end fastening ring 40 and the sample lower-end fastening ring 41 on the upper and lower ends of the sample heat-shrinkable sleeve 39, and then place the whole On the base 28 of the confining chamber;
[0131] Step 2: install the left displacement sensor 43, the right displacement sensor 44 and the axial displacement sensor 45 to form a displacement measurement system;

Embodiment 2
[0136] Example 2: True Triaxial Compression Test
[0137] In this embodiment, a true triaxial compression test is carried out on a rock sample, and the specific test operation steps are as follows:
[0138] Step 1: Lift the confining pressure chamber 5, and put the square rock sample 34 (the true triaxial test is a square column sample, and the lateral pressure is respectively rigidly loaded and hydraulic oil flexibly loaded) on the sample base pad 29 Place the left side pad 30 of the sample and the right side pad 33 of the sample on the left and right sides of the square rock sample 34 respectively, place the left side steel pad 4 of the confining pressure chamber on the left side of the pad 30 on the left side of the sample and At the same time, the left side spring 26 is placed at the bottom, the lower end spring 25 is placed under the right pad 33 of the sample, and the right steel pad 32 of the confining pressure chamber is placed on the right side of the pad 33 on the ri...

[0146] Embodiment 3: True and constant three-axis dynamic impact test test
[0147] In this embodiment, a true / normal triaxial dynamic impact test is performed on a rock sample, and the specific test operation steps are as follows:
[0148] Step 1: Refer to steps 1 to 3 in Example 1 for the installation steps of the conventional triaxial dynamic impact test sample;
[0149] Step 2: Apply the axial dynamic loading device 9 to the axial loading rod 8 through the axial dynamic loading pressure sensor 10, the dynamic loading force is 0-500kN, the frequency is 0-10Hz, and the amplitude is 0.5mm, realizing the conventional three-axis Dynamic shock test;
[0150] Step 3: Refer to steps 1-5 in Example 2 for the installation steps of the true triaxial dynamic impact test sample;
[0151] Step 4: Apply the axial dynamic loading device 9 to the axial loading rod 8 through the axial dynamic loading pressure sensor 10, the dynamic loading force is 0-500kN, the frequency is 0-10Hz, and th...
