| 摘 要： | 针对断层间距对隧道纵向稳定性的影响问题,采用FLAC3D计算模型分析应力及位移的分布规律.结果表明:断层间距越小,隧道纵向稳定性越差;断层间距不同,应力和位移纵向分布规律亦不同;顶板和边帮与断层相交区域为应力降低区,其前后为应力升高区,底板相反.

| Abstract: | The attempt to investigate the influence of fault space on longitudinal stability entails the simulation of the stress and displacement distributing rules by the finite-difference program FLAC3D.The numerical results show that the smaller of the space of fault was,the poorer longitudinal stability of the tunnel was; the stress and displacement longitudinal distributing rules varied with fault space,and stress-reducing region lies in the intersection region formed by roof,side and fault,with stress ascending... |
