Torque monitoring method for strong dynamic pressure tunnel high pre-stressed anchor rod and anchor cable combined support

The invention relates to the technical field of stress monitoring, and particularly discloses a strong dynamic pressure tunnel high-prestress anchor rod and anchor cable combined support torque monitoring method, which comprises the following steps: generating a strong dynamic pressure tunnel high-prestress anchor rod and anchor cable combined support structure model and a support layout model; all key pressure-bearing positions of the strong dynamic pressure tunnel at the current moment are determined, and a pressure-bearing dispersion mechanical model of each key pressure-bearing position at the current moment is determined; determining a plurality of torque monitoring positions and a torque monitoring direction of each torque monitoring position based on the pressure-bearing dispersion mechanical models of all key pressure-bearing positions at the current moment, and acquiring a torque variation of each torque monitoring position in a preset duration of the corresponding torque monitoring direction; the me
