Abstract: 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.

Key words: Longtan Tunnel, Shale, Optimization, Numerical Analysis
