AI Technical Summary
Existing technologies for determining the Poisson's ratio of rocks suffer from difficulties in overcoming the influence of the initial compaction process and stress level. The testing methods are complex and costly, making them difficult to widely apply in engineering.
By using uniaxial loading and unloading tests, the loading and unloading stress range of the rock was determined, and the axial and circumferential strains were recorded. The average Poisson's ratio of the rock was calculated, which simplified the test process and reduced equipment requirements and costs.
The obtained average Poisson's ratio of the rock has good numerical stability, conforms to the definition of the elastic constant of the material, is simple and easy to implement, and is suitable for testing in rock mechanics, mining engineering and engineering geology.
