摘要
利用ANSYS大型数值分析软件对引水隧洞TBM掘进段的施工及运营过程进行了三维数值模拟。采用生死单元,获得了隧洞在施工各个阶段的应力及位移释放情况。对数值计算结果进行了分析,得出一些有意义的结论,对大型隧洞工程的设计和施工具有指导意义。
Numerical analysis of the process of TBM construction and operation is studied for a tunnel by 3D-FEM of ANSYS.During calculating analysis,live and death elements were used to simulate excavation process of tunnel.The stress and strain state of surrounding rock and results of the displacement release in all stages were obtained.Through analysis of numerical result,some conclusion has been gotten for the design of the engineering and the technique support on large-scale deep tunnel.
