large-section tunnels

Based on the construction of Class III to V surrounding rock in the Wengjiashan Tunnel project, this study uses on-site experimental statistics and comparative analysis methods to investigate the construction efficiency of traditional manual work versus large-scale mechanical equipment during the

In view of the characteristics of two-way eight-lane and single-hole four-lane large-section tunnel construction of expressway, the application of large-scale mechanized full-process operation technology is studied. Through the use of advanced geological prediction technology, the condition of the
