Abstract Abstract: The article describes a new type of bi-directional excitation electric dynamic servo-control triaxial test machine, built-in diving- pressure compensation axial load sell, reducing the effects of friction, improved measurement accuracy. All digital electro-hydraulic servo control system may solve a problem which soil test process control response. When the volume deformation measuring equipment and electrical compensation system were fitted, the equipment can test for unsaturated soil. The programme of different diameter specimen electric auto-compensation can overcome the elements of the complex interaction of the problem in the soil triaxial test.
Key words: the triaxial testing machine��diving-cell��bi-directional excitation��remove coupling circuit
