Özet

The paper presents the geotechnical properties along the route of the 9,325 m twin tunnel metro route in the Greater Municipality of Ankara. Convergence measurements taken during tunnel construction are presented and discussed. In addition, the convergence of the twin metro tunnels was analysed by means of a 2D plane strain finite element (FE) analysis. The FE model estimations and the field measurements are compared.
