Stress path is different, generally for the strength parameters of soil c ', Ф 'value, the impact is not big, but for the deformation characteristics of soil is strong influence, or for an ideal homogeneous soil, both drainage and consolidation undrained, triaxial compression and triaxial extension of different stress paths, the effective strength index c, Ф median difference is not big, For anisotropic soil with layered structure of the soil sample, the intelligence of different stress path triaxial test, not only to produce a great impact on the strength parameters, and the deformation index will be a very big difference, so smart stress path triaxial test as a condition of a special triaxial test, for the engineering application research is noteworthy problems in practice.
The instrument is hydraulically operated servo-controlled, without the constant stress and constant strain automation of the triaxial pressure chamber of the pressurized frame.
