FULL-AUTOMATIC TRUE TRIAXIAL TUNNEL AND UNDERGROUND CONSTRUCTION MODEL TESTING SYSTEM

摘要

A full-automatic true triaxial tunnel and an underground construction model testing system, comprising a triaxial loading device for loading a model test body (39), an automatic data acquiring and analyzing device, a power system, and a control system. The triaxial loading device comprises a test bed, a vertical loading system, a horizontal forward and backward loading system, and a horizontal leftward and rightward loading system; the vertical loading system, the horizontal forward and backward loading system, and the horizontal leftward and rightward loading system apply triaxial pressure to the model test body (39); the test bed has the effects of supporting, fixing, and providing counter-force; the automatic data acquiring and analyzing device comprises an optical fiber sensor, an optical fiber monitoring system, a micro pressure box, and a strain block embedded in the model test body (39), so that acquisition of multi-physical field information, such as model stress, displacement, and seepage pressure, is achieved, and computer programs achieve real-time automatic information acquisition, and real-time data entry, analysis, drawing, and early warning processing on the multi-physical field information; the power system provides power required for the proceeding of testing; the control system controls the loading force of the vertical loading system, the horizontal forward and backward loading system, and the horizontal leftward and rightward loading system, and controls the test bed.
