Analysis on interacting of close-vertical underpass existing subway during construction
Close-vertical underpass existing subway is the hardest condition during civil subway construction. Taking Beijing Metro Line 10 vertical Underpass Metro line 1 as the project background, the paper focus on the interacting of the new building and existing tunnel during the whole construction process. Adopting Ansys and Flac-3d to build large-scale mathematical and physical artificial models, by the analysis of the new building and existing tunnel deformation and stress alteration we got the Mechanical Characteristic of the new and existing subway tunnel. The research indicates that the main affect range of the new tunnel construction to the old tunnel is mainly in double excavation scope (6m). The main characterizations of the existing tunnel include the liner stress decreased, incline and recover. The existing of metro line 1 takes block conductive effect to surrounding rock stress and deformation caused by excavation.
