Deformation Control and Influence of Deep Foundation Pit Excavation on Existing Metro Station at Transfer Station
Based on the influence of foundation pit construction on the existing subway station structure in a transfer station in Hefei,the whole process of foundation pit construction is simulated based on the fi-nite element analysis software MIDAS-GTS/NX,including foundation pit excavation,station and auxiliary structure reconstruction,side wall demolition and so on.The simulation results show that the horizontal and vertical displacement of the existing main body and auxiliary structure of the station and the section structure are all lower than the control value of 5 mm,meeting the requirements of the specification.Therefore,it can be seen that the existing subway structure can ensure safe operation in the construction process of the pro-posed subway station structure.
