Abstract :In the highway transportation network, the tunnel has an important place. Tunnels are used to provide safe, comfortable and economical transportation in areas where topography is not available. In addition to the facilities provided by the tunnels, there are various risks during and after the manufacturing phase. These risks need to be anticipated and manufacturing must be shaped to address these risks. Therefore, deformation analysis in tunnel projects has an important place. During and after manufacture, it is necessary to determine and follow the deformations.   In this study, Ayvacık - Küçükkuyu highway in Çanakkale will be dealt as T1 Tunnel between km 10 + 700 - 12 + 400. Due to the fact that the region is located on the earthquake zone and because of this reason it has a mixed lithology, it is very important to follow the deformations. In this context, it is aimed to analyze the relationship and dimensions of deformation factors in the structure by using geodetic and geotechnical measurement methods. The relationship between these data and the load, pressure and tension values observed on horizontal and vertical movements will be examined during the manufacturing process. Moreover, due to the fact that the zone is located on the earthquake zone, earthquakes that occur in the region during the manufacturing process and the manufacturing effects of these earthquakes will be investigated.   With this study, it is aimed to give guidance to manufacturing by predicting deformation and external effects that may occur and arise in engineering constructions. The required revisions should be made in the fortification systems in line with the predetermined parameters. In this way, it is aimed to ensure that the manufacturing process continues in the most economical and safest manner.
