| description | The invention discloses a composite stratum shield hob wear calculation method and device based on tunneling parameters and a medium, and the method comprises the steps: S1, based on a shield hob wear mechanism, according to tunneling parameters, geological parameters and cutterhead cutter design parameters, calculating friction factors between a hob and a soil body under different stratums in real time; and S2, according to the friction factor, in combination with stress analysis of the hob on the tunnel face, the abrasion loss of the shield hob is quantitatively determined in real time based on an energy method. The friction factor f between the hob and the soil body is inversely calculated according to shield tunneling parameters (the cutterhead torque, the tunneling speed and the cutterhead rotating speed), so that in the shield tunneling process, the abrasion height of the hob can be calculated in real time, the abrasion height is set according to previous engineering construction experience, and the con |
