Automatic Rock Test Coarse Soil Rock Sand Direct Shear And Triaxial Test Apparatus

This product is used to test and analyze the stress-strain relationship, deformation and strength characteristics of coarse grained soil under triaxial unequal stress conditions, and to study the numbering rule of deviatoric stress, volumetric strain and internal friction angle with S2 coefficient of intermediate principal stress. Because the conventional triaxial only considers the stress in S1 and S3 directions, and does not consider the influence of the intermediate principal stress, it cannot truly reflect the stress characteristics of the soil mass. In order to obtain the actual stress state of coarse-grained soil in the project, only through the true triaxial testing machine can the triaxial unequal stress be applied to the coarse-grained soil sample, and the actual stress characteristics of the land can be truly and accurately reflected.
