摘要
针对俄霍布拉克斜井开挖,结合原支护方案对破坏机理和变形规律进行了数值分析。结果表明,斜井穿越松散破碎岩层时,肩窝及拱顶下沉位移较大、两帮收敛严重、底板破坏明显。
Based on the excavation of inclined shaft,analyzed the deformation mechanism and control countermeasures of primary supporting scheme,conclud that the crown settlement and sides convergence and floor heave is severe in soft and cracked surrounding rock.
