Test device and method for simulating geological bias tunnel

The invention discloses a test device and method for simulating a geological bias tunnel, the test device for simulating the geological bias tunnel comprises a simulation box, an inclined rock stratum medium, an angle adjusting mechanism, a loading mechanism and a test mechanism, the inclined rock stratum medium and the angle adjusting mechanism are arranged in the simulation box, and the simulation box is supported on an inclined rock stratum; the angle adjusting mechanism is used for adjusting the inclination angle of an inclined rock stratum medium relative to the simulation box, the loading mechanism is arranged outside the simulation box and used for applying pressure to the simulation box, and the testing mechanism is arranged in a tunnel and used for applying disturbance to surrounding rock and collecting power data of the surrounding rock so as to achieve dynamic disturbance response testing of the tunnel. Therefore, the engineering problem in the tunnel excavation process can be predicted, the reliab
