Frozen soil tunneling test device and test method thereof

The invention discloses a frozen soil tunneling test device and a test method thereof, the frozen soil tunneling test device comprises a soil body unit, a refrigeration unit and a temperature measurement unit are arranged in the soil body unit, and the soil body unit is provided with a reaction frame for starting of a tunneling machine host. According to the technical scheme, the soil body unit, the refrigeration unit for simulating the frozen soil environment and the tunneling machine main machine for excavating the soil body unit are combined, and the excavation process of the tunneling machine in the plateau frozen soil geology is truly simulated; the refrigeration unit simulates frozen soil geology of different freezing degrees, the tunneling machine host simulates the real process of tunnel construction excavation in the frozen soil environment simulation system, and tests and demonstrates the adaptability of cutterheads and cutters, the matching relation between the excavation speed and the frozen soil
