摘要

Background to the Beijing Metro,based on finite element software PLAXIS,displacement and internal force of the single structure excavation are analyzed; based on finite element software ANSYS,comprehensive influence of accessory structure and existing structure are discussed in multi-tunnel effect.The results indicated that,internal force and displacement of single structure and multi-tunnel can meet the design requirements,The application of reasonable scheme can eliminate the influence of multi-tunnel effect.
