The invention discloses soil engineering triaxial shear test equipment based on an MTS electro-hydraulic servo tester. The soil engineering triaxial shear test equipment comprises the MTS electro-hydraulic servo tester, wherein a soil engineering triaxial shear testing device is mounted on an MTS electro-hydraulic servo tester upper chuck and an MTS electro-hydraulic servo tester lower chuck of the MTS electro-hydraulic servo tester. The soil engineering triaxial shear test equipment has the following technical effects as follows: an accurate and stable force source is provided through sufficient utilization of the MTS electro-hydraulic servo tester, perpendicular pressurization on a sample is realized through an upper fixing rod and an axial drive rod, increasing and stabilizing of the confining pressure and the back pressure of the sample are realized through matching of a fed liquid of a liquid feeding port and a pressure volume controller, finally, back pressure saturation, isotropy and anisotropy of consolidation loading and unloading circulation, K0 solidification, creep solidification and dynamic and static triaxial shear test of the sample can be performed on the sample through close matching of components, the test process is controlled through software, the operation is simple and convenient, the automation degree is high, and the soil engineering triaxial shear test equipment is suitable for research, popularization and application; the equipment is simple and compact in structure, convenient to assemble, low in cost, high in measurement accuracy and good in stability and occupies small space.
