摘　　要：选取龙潭隧道右线页岩地段为研究对象,用有限差分程序研究了该段施工过程中,不同开挖方法条件下围岩的受力和变形特征,通过对比分析,确定了该段施工的优化方案,方案安全有效,对类似工程具有一定的借鉴意义。Finite difference method was used as a tool to optimize tunnel construction through Shale bedrock for the right line of Longtan Tunnel. The stress and strain in the rock mass due to different excavation methods obtained from the numerical analysis were used as the basis in the selection of the final tunneling method.
