摘　　要：针对隧道开挖对框架结构的影响问题,应用有限元软件建立隧道开挖对框架结构的影响模型,计算隧道开挖引起框架结构的位移并加以分析,得出框架位移随施工阶段的变化规律。通过分析加深认识了隧道开挖对框架结构的影响问题,为进一步解决工程实际问题提供一定借鉴。In light of the impacts of tunnel excavation on frame structure, it establishes the influential model of tunnel excavation on frame structure by applying finite element software, calculates and analyzes the frame structure displacement owning to tunnel excavation, and finds out the frame structure displacement law at construction phase. Through the analysis, it further realizes the impacts of tunnel excavation on frame structure, which has provided certain referring value for further solving engineering problems.
