摘要
针对软岩巷道围岩变形量大,支护困难的特点,应用有限元软件对不同形状巷道进行数值模拟分析,得到不同形状巷道围岩应力分布规律、变形特点及支护材料上的应力分布规律,研究结果对生产实践有一定的应用价值。
The deformation of soft rock tunnel is big, and that tunnel is digicult to support. In order to study on the engineering problems fur- ther more, finite element software is used to analyze tunnels of different section shape. The disciplines of surrounding rock stress distribution, deformation characters, and stress distribution of support material are achieved. The study results have some application value to engineering field.
