Focusing on the complex geological hazard challenges—including high ground stress, rockburst, large deformation, water and mud inrush, and high ground temperature—confronted by the Kangding Spiral Tunnel Group of Route G4218 (situated adjacent to the Xianshuihe Active Fault Zone, and being China's largest and highest-altitude single-layer deep-buried extra-long spiral tunnel under construction), this research, grounded in the division of rock mass structural damage zones, employed integrated geological investigation techniques with cross-validation of multiple methods. It systematically ascertained the engineering geological issues of the tunnel group, with notable investigation effectiveness. Through comparison with construction disclosure, the reliability of key investigation conclusions was confirmed, and the causes of discrepancies were analyzed in depth. The study shows that: For surveys of long, deep-buried tunnels in complex geological contexts, a sophisticated “zoning-subsection” investigation system should be established, and multi-dimensional information collection and cross-validation analysis should be enhanced to guarantee the scientific credibility of conclusions. The findings offer a systematic basis for the design and optimization of investigation schemes for similar tunnels.
