Abstract

The invention discloses a full-automatic three-axis testing system for a saturated soil stress path. The full-automatic three-axis testing system comprises a pressure chamber (1), a computer (2), an axial force volume controller (3), a confining pressure volume controller (4), a back pressure volume controller (5), a data acquisition box (6) and a pressure volume control system connected with the computer (2). The full-automatic three-axis testing system for the saturated soil stress path is reasonable in structural design, convenient to operate, high in automation degree and good in stability and can be used for accurately controlling a complicated stress path of a soil body.

Description

Technical field [0001] The invention relates to a test instrument for testing the deformation and strength characteristics of saturated soil, in particular to a triaxial test system capable of accurately simulating the stress path of the soil body, automatically processing test data, and generating test charts in real time. Background technique [0002] The triaxial instrument is a geotechnical test instrument used to test the deformation and strength characteristics of the soil. The triaxial test considering the real stress path of the soil can establish a constitutive relationship that reflects the real mechanical behavior of the soil in situ. It is very useful for scientific research and civil engineering design. has great significance. [0003] The automation degree of the triaxial instrument in the prior art is very low, and some rely entirely on manual operation, and the function of simulating the stress path is poor, or even does not have such a function. For example...
