Ring Shear and Seepage-Coupled Apparatus and Ring Shear and Seepage-Coupled Test System for Rock and Rock Fracture under Tension or Compression Stress
Ring Shear and Seepage-Coupled Apparatus and Ring Shear and Seepage-Coupled Test System for Rock and Rock Fracture under Tension or Compression Stress
A ring shear and seepage-coupled apparatus and a ring shear and seepage-coupled test system for rock and rock fracture under tension or compression stress are provided, relating to the technical field of mechanical testing devices. As to the ring shear and seepage-coupled apparatus, an axial piston rod is connected with an upper shear box, a torque transferring shaft is connected with a lower shear box, an axial force transducer is provided on the axial piston rod, a torque transducer is provided on the torque transmitting shaft, and a force transferring plate is fixedly connected onto the upper shear box. The force transferring plate is able to transmit a counter force for exerting a torque. Radial and circumferential seepage tests can be achieved by providing a seepage structure. The ring shear and seepage-coupled test system comprises a servo pump and the ring shear and seepage-coupled apparatus as mentioned above.
