在有限元软件ANSYS平台上,建立了不同净距下水工双线隧洞的数值模型,通过研究洞间净距对隧洞外围围岩位移及应力分布的影响,对围岩的稳定性进行了分析,得到适用于相近水工隧洞工程的合理净距建议值。
On the ANSYS platform of finite element software, a numerical model of double-line tunnel with different spacing distance is established. The stability of the surrounding rock is analyzed by studying the influence of clearance between the tunnels on the displacement and stress distribution of the surrounding rock. , To obtain a reasonable clearance for the similar hydraulic tunnel project recommended value.
