Analysis on the Influence of Road Supporting Engineering Construction on the Operating Subway Station
The construction requirements in the protected area of the operating subway are high,the soil covering above the subway station is shallow,and the influence of unloading on the existing structure is obvious.Taking the municipal supporting engineering across the subway as an example,this paper studies the influence of construction on the deformation and anti-floating stability safety factor of existing subway structure through finite element analysis and anti-floating checking calculation.From the calculation results,it can be seen that the excavation unloading has obvious influence on the vertical deformation of the structure,and the influence of the roof beam demolition on the anti-floating stability of the subway structure meets the requirements of the specification.The comparison between numerical simulation data and monitoring data shows that the simulation results are consistent with the actual situation,which can provide some reference for similar engineering.
