The New Austrian Tunneling Method (NATM) is a modern tunnel construction technique that focuses on continuous monitoring and real-time adjustments as the tunnel advances. This approach allows engineers to adapt the support system to actual ground conditions, improving safety, stability, and cost efficiency. One key principle behind NATM is utilizing the surrounding rock mass as a natural support structure, rather than depending solely on concrete linings or steel reinforcements. By observing and

🔵 New Post 🚀 The New Austrian Tunnelling Method (NATM) is based on the principle of mobilising the ground’s inherent strength to ensure stability. The diagram illustrates a double core excavation sequence, where the tunnel is divided into top heading, bench, and invert sections. Sequential excavation and immediate application of shotcrete with lattice girders and rock bolts allow stress redistribution, minimising deformation. The field image shows the practical implementation of this method, h

The New Austrian Tunnelling Method (NATM) is a versatile and innovative approach adaptable to a wide range of geological conditions. It can be effectively applied in soft ground, soft rock, or hard rock environments. The method involves excavating tunnels in small sections and immediately supporting them with shotcrete, steel ribs, and wire mesh to strengthen the structure. At MEIL Group, we adopt NATM to deliver vital tunnel projects across the country, ensuring world-class infrastructure is bu

It took six years, 11 tunnel boring machines (TBMs) and 13,000 people to construct the Channel Tunnel. 🚇 This year, we celebrate 30 years of the world’s longest undersea crossing. #ThenNowTomorrow At a staggering 50.5km, it remains the largest and one of the most difficult underground construction projects undertaken in UK #engineering history. We took the helm as lead designers for the UK side of this monumental project. An innovative approach at the time made it possible to: ✅ Design a unique
