Abstract

With large-scale construction of subway lines, the influence of subway excavation to the frame structure has been an common problem to be solved. Finite element software was used to create three-dimensional model of the subway with different horizontal distance to the frame structure, and variation of frame structure’s bending moment, axial force, shearing force caused by subway excavation is obtained to analyze. The results will enable engineering staff to have a more comprehensive understanding on this issue, and provide guiding significance for solving similar engineering problems to some extent.
