@designexpertint: New Austrian Tunneling Method: how tunnels are built in stages under demanding ground conditions 🏗️⛰️ Not all tunnels are excavated in a single pass. With the New Austrian Tunneling Method, the tunnel section can be divided into stages so the ground is supported as construction advances using shotcrete, rock bolts, and deformation control. 🚇🪨📐 This method is essential for tunnels with variable geology, large cross-sections, or urban conditions where ground stability must be closely monitored. Did you know a tunnel can be built in stages to improve safety and control? 👷‍♂️⚙️ #tunneling#civilengineering#geotechnicalengineering#construction#infrastructure#undergroundconstruction#tunnelengineering
