The system has the stably control function of danymic-static,loading axially,surrounding pressure and pore water pressure for seismic simulation study, which could confirm the intensity,shear modulus,damping ratio of soil mass. The study of stress path can be setting by the stress path testing control system, and the triaxial creep testing can be setting by the triaxial creep testing control system.
