The Relation of the Method Used in Tunneling Operations with the Geological Structure Example of the Black Sea Coastal Road

Transportation tunnels are the most preferred method to facilitate transportation in mountainous and rough terrains. The excavation choice of fortification tools tunnel construction depend on geological structure route. Correct formation determination will reduce cost eliminate many risks. Black Sea region has a very rugged terrain. obvious used overcome terrain is road tunnels. rock classification route support be formed accordingly important selection applied highway constructions. Within scope this study, Trabzon-Akyazi region, which an part coastal road, was studied. formations 3-lane double-tube with length approximately 2476 meters, planned built within passing through were examined determined. As result analyzes calculations, it been determined that dominant unit along routes agglomerate Besirli New Austrian Tunneling (NATM) applicable. classes found B3 C2 according NATM. Excavations carried out by drilling blasting form upper half lower half.
