为了分析采空区隧道变形稳定性问题，隧道围岩变形特性研究显得十分重要。首先利用虚拟现实软件MultiGen Creator对一破坏的采空区隧道支护结构进行三维仿真模拟计算，并对其破坏情况进行统计分析。然后，借助三维有限差分软件FLAC3 D对同一采空区隧道进行数值模拟计算。通过把模拟计算结果与统计结果进行对比，发现数值模拟与统计结果基本一致。结果表明采空区的存在对隧道的变形稳定性影响很大，这将对采空区隧道后期的支护加固治理提供有益参考。

To solve the problem of the deformation stability of the tunnels in mined-out areas ,it is necessary to study the deformation characteristics of the surrounding rocks of the tunnels .Firstly ,with the help of the virtual reality software MultiGen Creator ,the three-dimensional supporting structure of a damaged tunnel was simulated ,and the destructive sta-tus of the supporting structure was analysed statistically .By adopting the three-dimensional finite differential software FLAC3D ,the numerical simulation of the same tunnel was calculated simultaneously .It was found that the numerical sim-ulation and the statistical results were basically identical by comparing the calculated results with the statistical results . This indicate that mined-out areas have a great influence on the deformation stability of the tunnels running through them , and this conclusion will provide beneficial reference to the later reinforcement and management of the supporting struc-tures of the tunnels in the mined-out areas .
