The growing reliance on subterranean infrastructure, spurred by the expansion of urban landscapes, the escalating population densities, the pressing need for efficient transit systems, the many environmental imperatives, and spatial constraints on surface development accentuate the pivotal role of metro tunnels akin to those found in Shiraz. These tunnels, crafted, using Earth Pressure Balance (EPB) and Tunnel Boring Machines, and fortified with segmental linings, undergo meticulous scrutiny for displacement and stability, employing static and quasi-static methodologies. Employing the sophisticated FLAC 2D software, the investigation delves into the nuanced impact of altering segmental lining thickness on displacement dynamics. Analysis results unveil a notable augmentation in displacement under quasi-static conditions, notably accentuated when the lining thickness is reduced. [ABSTRACT FROM AUTHOR] |
