摘要
利用ANSYS7.0有限元分析软件对TBM法隧道施工的过程进行数值模拟分析。结合隧道的工程地质情况,分析其应力应变的状态,提出了ANSYS模拟不同施工阶段围岩应力应变的变化规律的可行性,并将此结果成功地应用于昆明上公山引水隧道的TBM卡机分析中。
The process of TBM tunnel construction is analyzed by numerical simulation with ANSYS 7.0. Combining with the geology of the tunnel, the feasibility of simulating the variation of train and stress in the different stage of construction in the surrounding rocks by ANSYS is put forward. Meanwhile it is used successfully in the analysis of TBM jamming in Shanggong mountain tunnel.
