Geological investigation and surrounding rock classification ahead of tunnel faces are among the most critical fundamental tasks in tunnel construction. However, current methods for obtaining rock mass parameters and conducting grade evaluation are plagued by significant subjectivity, prolonged cycles, and insufficient intelligence. To address these issues, this study takes the Shitang Tunnel, Zaoxi Tunnel, Jiangjunshan Tunnel, Kuiba Tunnel, Dapingwei Tunnel as engineering cases, integrating geological survey data from tunnel faces and ground penetrating radar (GPR) advance detection data. A d...
