New Austrian Tunneling Method (Natm): A Flexible Solution For Complex Tunneling

New Austrian Tunneling Method (NATM) is a construction technique used to excavate tunnels by dividing the excavation into small sections and installing support structures as the excavation progresses. NATM relies on passive support, such as rock bolts and shotcrete, to stabilize the surrounding rock mass instead of relying solely on heavy temporary supports. This method allows for flexibility in design and construction, making it suitable for complex geological conditions.
