摘要
以某具体工程为背景,采用有限元数值模拟分析软件ANSYS,对明挖法施工方案从基坑开挖施工全过程来研究基坑开挖对下方盾构隧道变形的影响。经实测,采用三维数值模拟能很好地模拟基坑开挖过程,所得结果与实测结果吻合较好。
With the background of some project,the construction plan of cut & cover method is researched on its influence to the deformation of shield tunnel below from the whole process of foundation pit excavation by finite element numerical simulation analysis software ANSYS.Through a practical measurement,3D numerical simulation can simulate the process of foundation pit excavation greatly and the obtained results can match the measured ones as well.
