Surveying works during the construction of the Čortanovci tunnel

Abstract

Underground structures in the form of tubes open at both ends, placed horizontally or vertically on a slight slope, and through which a road passes: railway, road, canal, or waterway, which connect two parts of the road separated by an obstacle, are called tunnels. During the design and construction of tunnels, geodetic works are carried out following legal regulations. Attention should be paid to the geodetic basis, as well as to the tunnel marking network to perform reconnaissance and stabilization of points in a high-quality manner. Further works include the marking of points, as well as their control, then calculations and data transformations to obtain the coordinates in the global coordinate system. This paper presents the mentioned works during the construction of the Čortanovci tunnel.
