Abstract
In this paper the different methods and implications of full-face tunnel excavation in soils are analysed through numerical FEA (Finite Element Analysis) software and compared with construction monitoring data, empirical predictions and previous analysis from studied literature. A 2D plane strain analysis of a section of the Milan metro-line 5 was conducted under free field conditions using PLAXIS software to display its impact on ground settlements and deformation around the tunnel face. The results found that the FEA model produced an accurate prediction of the settlement troughs, impact of the grouting pressure, and construction of the second tunnel tube on the final induced settlements. Empirical prediction equations were also used to fit Gaussian curves against the numerical curves which produced an accurate alignment of trough width to the numerical prediction.
