Abstract

The existing metro station buildings closest to the cover excavation pit will inevitably be more damaged as a result of pit construction. A three-dimensional finite element model was created using ANSYS software based on a deep foundation pit adjacent to an existing metro station in Beijing to simulate the cover excavation pit construction process and discuss the impact of the pit construction process on the deformation of the attachment structures of the existing station. The distance between the existing structure and the new pit, as well as the shape of the existing structure and the connection between the attachment structure and the main station, all play a role in how much the existing station attachment structure is impacted by the tendency to sink during pit construction.
