Abstract
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.
Résumé
L’article présente les propriétés géotechniques des terrains le long du tracé du tunnel bi-tubes du métro à Ankara. Les mesures de convergence réalisées durant la construction des tunnels sont présentées et discutées. De plus, cette convergence a été modélisée à partir d’une méthode aux éléments finis, à deux dimensions, en déformation plane. Les résultats de la modélisation et les mesures de terrain ont été comparées.
