摘　　要：近地铁立交项目的施工在城市化扩展的今天已无可避免。面对这一复杂工程问题,以丰台火车站站房东侧立交专用匝道工程为例,叙述其与地铁10号线间的关系,并给出具体数值模拟各施工步的方法。经过计算与后期实际测量结果对比,计算拟合程度较好,这些方法对日后类似的复杂工程有着一定的借鉴意义。The construction of the near subway interchange project is inevitable in today’s urbanization expansion. Tianjin Faced with this complex engineering problem, this paper takes the landlord side interchange ramp project of Fengtai Railway Station as an example to describe its relationship with Metro Line 10, and gives specific numerical simulation methods for each construction step. After calculation and comparison with the actual measurement results in the later stage, the calculation fit degree is good. These methods have certain reference significance for similar complex projects in the future.
