Analysis on Deformation and Internal Force of Reserved Wall Structure for Removing Station Transfer Nodes
With the development of rail transit,the density of the line network will increase,which will lead to an increasing number of transfer stations.The connection between the newly built transfer station and the existing station has become an important design content,and the construction of abolishing the walls of the existing operating station has become an important key technology.On the one hand,it is necessary to ensure the safety of the existing line operation,and on the other hand,it is necessary to ensure that the stress of the existing subway structure is within the normal range.Taking a newly built transfer station as an example,ANSYS finite element analysis software is used to simulate the construction of chiseling out the side walls of transfer nodes in order to acquire the deformation and internal force changes of the existing structures.The corresponding technical measures are proposed from the design and construction aspects.
