A system and method for advanced detection and repair of areas with a high number of fractures
By using an advanced detection and repair system, the deviation between the detected cracks and the actual geological cracks during tunnel construction is corrected in real time, ensuring the safe passage of the tunnel through areas with many cracks and solving the safety hazards caused by detection errors.

Abstract
The application provides an advanced detection and repair system and method for crossing a region with many cracks. The system comprises a crack detection unit, a crack repair unit and a working face advancing unit. The crack detection unit collects geology within a transverse Xm range of the working face, the crack repair unit reinforces cracks within a transverse X1m range to obtain first repaired cracks, X1 < 0.5X, the working face advancing unit advances the working face by X2m to obtain a new working face, X2 < X1; the crack detection unit collects geology within the transverse Xm range again, the crack repair unit adjusts the crack repair scheme and reinforces cracks within a transverse X-X2 range to obtain second repaired cracks; and the working face advancing unit advances the working face by X3m to obtain a new working face again, X3 < X-X1. The advanced detection and repair method is based on the advanced detection and repair system. The application adopts a mode in which the advanced detection range is greater than the crack repair range, and the crack repair range is greater than the working face advancing distance, to solve the deviation problem between the detected cracks and the actual cracks in geology.
