Large-scale 3D simulati on of rock-mass deformation under static-dynamical coupling loading

  • 摘要: 为了探讨地下巷道围岩破坏过程与机制,利用自制的大型三维立体模拟装置与 “ 声–光–力 ” 多元指标实时测试系统,完成了恒定与可变围压下的 “ 动–静 ” 耦合加载试验。对宁夏鸳鸯湖矿区复杂地质模型开挖中扰动区内围岩内部裂隙发育、损伤及破坏形态进行光学 LCD 式内窥摄影和结构演化过程进行实时追踪,对围岩局部化损伤的声发射特征规律进行对比分析。试验结果表明,在不同载荷和开挖时步条件下,复杂围岩变形与破裂在不同加载阶段、不同层位有着一定的相似性和渐变性,而声发射活动经历 “ 贫瘠期 - 活跃期 - 回档期 - 沉寂期 ” 后,事件数减少,持续时间增长,围岩极有可能会出现局部衍生灾害,进一步揭示了复合围岩局部持久性变形特征。
    Abstract: To explore the damage process and mechanism of underground roadway, by using a large-scale three-imensional simulation device and a real-time test system with acoustic-optics-pressure multiple indicators, dynamic-static coupling loading is completed under constant and variable confining pressures. The crack growth, damage and failure modes as well as the evolution process of structures in the region of excavation disturbance surrounding are real-time tracked by LCD-type optical endoscopic photography in complex geological model of Yuanyang Lake mining area, Ningxia, and the rules of acoustic emission in localized damage in surrounding rock are analyzed. The results show that complex rock deformation and fracture at different loading stages and different horizons have certain similarity and gradual nature under different loading weights and excavation steps. After the acoustic emission events have undergone barren period-active period-back to schedule-quiet period, the number of events begin to reduce, the endurance period grows, and partial derivative disasters are most likely to appear, which further reveals the local deformation characteristics of the persistence in the complex surrounding rock.
