Discussion

This assessment reveals how blasting affects structural stability in tunnels, indicating significant risks for adjacent structures.

Blasting can compromise the structural stability of newly-built tunnels and nearby tunnels, increasing risk factors.
Analysis showed over 85% accuracy in matching measured excavation contours with finite element simulation results.
Self-developed detection devices were used to collect detailed data on overbreak and underbreak distributions.
The results suggest careful consideration of tunnel lining positions during blasting to mitigate structural risks.

Li et al. (2025) studied this question.
