The occurrence of subsidence during the driving of surface near tunnels, particularly those associated with urban transport schemes, is a widespread phenomenon that is influenced by various factors such as the type of ground and rock structure, tunnel dimensions, excavation methods, and support systems. This paper focuses on the Niyayesh tunnel, situated in the alluvial zone of Tehran, Iran, where a support system comprising a latex membrane, welded wire mesh, and 5-centimeter-thick shotcrete is employed. To measure subsidence, a combination of settlement points, convergence pins, geodetic points, extensometer rods, crack meters, and strain gages are utilized. The study specifically investigates how variations in excavation speed, tunnel support type, and ground conditions impact subsidence at a tunnel bifurcation with an opening width of 32 meters. This comparative analysis reveals significant insights into the interplay between these factors and their collective effects on subsidence in urban tunneling contexts.
