Investigation Into Structural Behaviour of Concrete Lining of New Austrian Tunneling Method (Natm) Vis?A?Vis Use of Tunnel Boring Machine (TBM)
Author(s): Sanjivanee Kamble*, Patil AV and Harshavardhan Deshpande
NATM is a design philosophy as well as a construction process. The idea is to reinforce the tunnel construction as much as possible by utilizing the strength of the surrounding earth. Put another way, the tunneling process is dictated by the ground conditions. Constant monitoring is also encouraged by the NATM ideology. The study investigates the structural behavior of concrete linings in Mumbai Metro Line-3's Sahar Road crossover, focusing on the comparison between the New Austrian Tunneling Method (NATM) and Tunnel Boring Machine (TBM) utilization. The research aims to understand the effectiveness of these methods in ensuring the integrity and stability of tunnel constructions. The research compares various load combinations at different sections and parts of the crossover. Stress resultants, including axial force, moments, and shear forces, are analyzed using STAAD Pro software.. View More»
