摘　　要：为研究拟建高层建筑施工过程对下穿隧道的影响,采用有限元计算方法,分析高层建筑基坑开挖及上部主体施工不同工况下,下穿隧道位移及内力变化情况,进而研究变化情况对隧道的影响程度。结果表明可通过不同工况下隧道累计变形量作为判断项目实施可行性的依据。To study the influence of the construction process of the proposed high-rise building on the underpass tunnel, the finite element calculation method is used to analyze the displacement and internal force changes of the underpass tunnel under different working conditions of the foundation pit excavation and the upper main body construction of the high-rise building. The influence degree of the change on the tunnel is studied. The results show that the cumulative deformation of tunnel under different conditions can be used as a basis for judging the feasibility of project implementation.
