Tunnels are subjected to complex forces and environmental conditions that can lead to structural stress, deformation, and other risks. SHM provides nearly real-time data on the structural behavior of tunnels, enabling engineers to make informed decisions and mitigate potential hazards efficiently. Effective\u00a0<strong>monitoring of tunnel construction<\/strong>\u00a0is essential to address these challenges.<\/p>\n<p><\/p>\n<h2 id=\"h-the-role-of-shm-in-tunnel-excavation\" class=\"wp-block-heading\">The Role of SHM in Tunnel Excavation<\/h2>\n<p><\/p>\n<p>Tunnel excavation is a challenging engineering task that requires careful planning and execution. The stability of the surrounding soil or rock, as well as the integrity of temporary and permanent support systems, must be continuously monitored to prevent structural failures and ensure safety.
