Research on Deformation Control Indicators and Standard of Urban Traffic Tunnel Construction Adjacent to High-rise Building


The biggest environmental problem caused by the construction of tunnels adjacent to high-rise buildings is the settlement of buildings. The paper analyzes the influence of tunnel excavation on the deformation of the superstructure and the deformation mode of the superstructure. It introduces the indicators and standards for the construction control of tunnel adjacent to the building at home and abroad. Combined with the Yuzhong tunnel project under construction in Chongqing, the main monitoring indicators and control standards of the Yuzhong Tunnel passing through the main buildings are given after comprehensive analysis and considerations, which provide a reference for the deformation control indicators of similar urban traffic tunnels adjacent to high-rise buildings.
