PREDICTIONS OF TUNNEL INDUCED MOVEMENTS - EXAMPLES FROM THE ATHENS METRO
The importance of the main geotechnical parameters affecting the results of two-dimensional plain strain tunnel analysis with the finite element method is presented. The effects on the surface settlement predictions of the strength and deformation parameters, the initial coefficient of earth pressure at rest, and the assumed relaxation factor of the rock mass before the application of the temporary support are examined for a typical configuration of the Athens metro tunnel. Settlements measured in the center of Athens are presented and combinations of parameters giving reasonable predictions are examined. The limitations and capabilities of back analysis are discussed.
