| 摘 要： | 基于自稳隐形拱理论,解释了巷帮支护对巷道围岩稳定性的重要性。运用MIDAS/GTS软件,进行了三维的模拟分析,选取了下帮滞后支护和正常支护2种模型,得出了前者比后者巷帮位移量、塑性区面积均大。现场监测结果表明:下帮表面位移量比上帮最大值大114mm左右,再次验证了下帮支护对巷道稳定的影响,为工程实践提出依据。

| Abstract: | Based on the theories of self-stabilized hidden arch,explaining the importance of sides support to the stability of surrounding rock.Using the MIDAS/GTS software,selected two model which is the under-sides hysteresis support and the normal support,the former sides displacement and plastic zone is bigger than the latter one.Field monitoring results show that: the surface displacement of under-sides is bigger than up-sides 114mm,verified the influence of under-sides support to the stability of surrounding rock,this paper proposes the basis for the engineering practice. |

| Keywords: | self-stabilized hidden arch the under-sides hysteresis support numerical simulation |
