Abstract

The invention discloses a seepage field-temperature field simulation coupling material bin and a TBM cutting test stand. A first bearing platform is circumferentially arranged on the inner wall of a body of the simulation coupling material bin, a second bearing platform is circumferentially arranged on the outer wall of a material mounting base, and the material mounting base is embedded into the body. The second bearing platform and the first bearing platform are in contact to be positioned, and the material bin body is divided into a closed containing cavity located between the first bearing platform and a base plate of the material bin body and an opened containing cavity above the first bearing platform. A seepage collecting branch is communicated with the opened containing cavity, and a heating water injection branch and a water returning and pressure maintaining branch are communicated with the closed containing cavity. The TBM cutting test stand comprises the seepage field-temperature field simulation coupling material bin. The seepage field-temperature field simulation coupling material bin can simulate a rock seepage field-temperature field coupling effect, and the TBM cutting test stand can make a TBM rock breaking experiment under the independent action of the seepage field and the temperature field or the coupling action of the seepage field and the temperature field. The seepage field-temperature field simulation coupling material bin and the TBM cutting test stand are reasonable in structure and convenient to operate.
