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.
