Research on the Impact of Construction of Subway Vertical and Horizontal Channels on Existing Overbridges
The construction of subways in the central urban area often adopts mining methods,and the construction of vertical shafts and horizontal passages as construction work channels will inevitably have an impact on the surrounding environment.Based on the construction project of a large-sized vertical shaft and horizontal passage of a tunnel on Beijing Metro Line 22,numerical simulation methods are used to finely simulate the layered and step-by-step excavation construction of the vertical shaft and horizontal passage.The deformation law of the existing pedestrian overpass under the influence of construction is studied,and active synchronous lifting technology is proposed,providing reference for similar projects.
