NATM Full Form In English
NATM is a modern tunneling technique used in civil engineering for constructing tunnels. It focuses on utilizing the surrounding rock or soil to support the tunnel structure, reducing the need for heavy support structures. The method involves careful monitoring, excavation in stages, and applying shotcrete, anchors, or steel ribs to ensure tunnel stability. NATM is widely used for road, railway, and metro tunnels due to its cost-effectiveness and adaptability to different ground conditions.
NATM Full Form In Hindi
NATM एक आधुनिक सुरंग निर्माण तकनीक है जो सिविल इंजीनियरिंग में उपयोग की जाती है। इसमें सुरंग की संरचना को सहारा देने के लिए आसपास की चट्टान या मिट्टी का उपयोग किया जाता है, जिससे भारी सहारा संरचनाओं की आवश्यकता कम हो जाती है। इस पद्धति में चरण-दर-चरण खुदाई, निगरानी और शॉटक्रिट, एंकर या स्टील रिब्स का उपयोग करके सुरंग की स्थिरता सुनिश्चित की जाती है। यह तकनीक सड़क, रेलवे और मेट्रो सुरंगों के निर्माण में व्यापक रूप से उपयोग की जाती है।
