Analysis of the Impact Mode of Urban Tunnel Undercrossing Existing Buildings
At present,there is an increasing density of buildings and structures in the central urban areas,and the number of new urban under-ground tunnels passing through existing buildings is increasing.To ensure the safe use of existing buildings and structures,it is necessary to analyze the interaction patterns between new and old structures.This article relies on a newly constructed urban tunnel project and uses finite element analysis software to analyze the impact mode of the construction process and operation status of the new tunnel project on existing build-ings in accordance with current national industry norms and standards,including the settlement,settlement difference,and surface deformation of the existing building foundation.The results indicate that the construction of new tunnels has a relatively small impact on existing buildings and does not affect their normal use,and the overall risk is controllable.
