1. Definition of rock triaxial testing machine
The rock triaxial testing machine is a testing equipment capable of applying three-dimensional stress (axial stress and two lateral stresses) to rock samples. Through this test, mechanical parameters such as rock strength, deformation characteristics, and failure modes can be measured, providing reliable data for engineering design and scientific research.
2. Working principle of rock triaxial testing machine
The working principle of the rock triaxial testing machine is to apply three-dimensional stress to the rock sample through the hydraulic system and measure the deformation and damage process of the sample at the same time. Here is a brief description of its workflow:
| steps | Description |
|---|---|
| 1 | Place the rock sample into the pressure chamber of the testing machine |
| 2 | Lateral pressure (confining pressure) is applied via the hydraulic system |
| 3 | Apply axial pressure until the specimen fails |
| 4 | Record the stress-strain curve and failure mode of the specimen |
