The invention relates to a tunnel structure disaster detection early warning model test device which comprises a model box, a model tunnel, a pressurization unit and a data acquisition unit. The model tunnel is arranged in the model box, and simulated soil is filled between the inner wall of the model box and the outer wall of the model tunnel; the pressurizing unit comprises clamping plates, reinforcing steel bars and ropes, the clamping plates surround the periphery of the model tunnel to form a ring, every two adjacent clamping plates are connected in an embedded mode through teeth arranged at the ends, the reinforcing steel bars are arranged at the ends of the clamping plates, one ends of the ropes are fixed to the reinforcing steel bars at the ends of the clamping plates, and the other ends of the ropes penetrate out of the model box to be connected with the traction device. The rope pulls the annular clamping plates to contract, and the model tunnel is pressurized through the simulated soil; the data ac
