Scope

Scope: This document specifies the technical process for true triaxial testing of rocks, including specimen preparation, specimen encapsulation, test procedures, and test data organization. It also stipulates the test techniques and methods for true triaxial compression deformation failure tests, true triaxial stress path effect tests, true triaxial compression rheological tests, and true triaxial uniaxial shear tests of rocks. This document is applicable to the determination and study of mechanical properties (parameters) of rocks under true triaxial stress conditions. Main technical contents: 1. Scope 2.
