高地应力隧道开挖过程中围岩稳定性分析

利用数值分析方法及FLAC3D软件对方斗山深埋隧道开挖进行数值模拟研究，分析了高地应力下隧道开挖围岩位移变化规律，指出了高地应力条件下围岩变化规律与常规条件下的不同，为指导施工提供了科学依据。

Analysis on the stability of surrounding rocks in the process of the excavation of high ground stress tunnel

In the article uses the numerical analysis method and FLAC3D software to research Fangdou mountain bury tunnel excavation to conduct the value simulator study deeply, has analyzed under the high crustal stress the tunnel excavation adjacent formation displacement change rule, had pointed out under the high crustal stress condition under the adjacent formation change rule and the conventional condition difference, has provided the scientific basis for the instruction construction.
