3D Modelling of a Tunnel Re-excavation in Soft Ground
Original language description
This paper describes numerical modelling of the tunnel re-excavation through the collapsed area. Ini-tial calculations of the tunnel re-excavation were made using a 2D finite element method. Subse-quently, further calculations to evaluate the rock mass behaviour in the collapsed area were provided in 3D. The 2D calculations were used to provide sensitivity studies, while 3D modelling was mainly used for evaluating the tunnel face stability (impact of the pile walls, impact of ground improvement) together with other factors (length of advances, moment of the temporary invert closure, etc.) The re-sults of the modelling were compared with the monitoring results. The paper also briefly describes the construction experience (technical problems, performanceof vari-ous support measures, etc.).
