AI Technical Summary
When tunnel boring machines (TBMs) are turning in the tunnel or when the tunnel segments are floating, it is difficult to maintain the design axis during tunneling, which poses safety risks and problems with unstable control of the point of convergence.
By obtaining the actual position of the tunnel boring machine, the design axis, and the segment float, the planned tunneling trajectory is calculated, and the correction torque is adjusted to match the actual position with the planned trajectory. The correction torque adjustment is optimized by combining machine learning models, and the state of the hydraulic cylinder is controlled to ensure stable propulsion.
It reduces the safety risks of the tunnel boring machine maintaining its design axis during tunnel turns or segment uplift, improves construction safety and automation, and reduces the impact of human factors.
