Abstract: When reconstructing metro stations for interchange, it is necessary to ensure the structural safety and operational safety of the existing operation station. Taking Hefei Rail Transit Line 1 Yungu Road Station side wall reconstruction as an example, a reconstruction scheme of side wall opening single hole at one time is proposed, and three-dimensional finite element software is adopted to calculate and analyze the existing station internal force redistribution and deformation under various working conditions. The checking calculation results show that the proposed reconstruction scheme can meet the structural safety requirements of the existing station.
