A fully automatic true triaxial tunnel and underground engineering model test system, comprising a three-axis loading device for loading a model test body (39), an automatic data acquisition and analysis device, a power system and a control system; the three-axis loading device comprises a test bench Frame, vertical loading system, horizontal front and rear loading system and horizontal left and right loading system, vertical, horizontal front and rear and horizontal left and right loading systems apply three-way pressure to the model test body (39); the test rig has the function of supporting, fixing and providing reaction force The data automatic acquisition and analysis device includes a fiber optic sensor embedded in the model test body (39), an optical fiber monitoring system, a micro pressure box and a strain brick, which can realize collection of multi-physics information such as model stress, displacement, and osmotic pressure by the computer. The program realizes real-time automatic acquisition of information, real-time data entry, analysis, drawing and early warning processing of multi-physics information; the power system provides the required power for the test; the control system controls the vertical, horizontal front and rear horizontal and horizontal loading systems Load force and control test bench. |
