采用实验和数值模拟相结合的方法研究静应力和爆破扰动所诱发的巷道围岩渐进破裂过程.研究结果表明:围岩的损伤程度由静应力加载和爆破动力扰动的双重作用所致,不同侧压力系数条件下静应力加载和爆破动载扰动条件下巷道围岩损伤破坏具有明显的差异性.初始应力条件控制着巷道围岩破坏区域的分布特征,爆破扰动会加剧巷道围岩的损伤深度和失稳破坏速度.垂向和水平静应力差值越大,爆破扰动造成的巷道损伤程度越大.爆破结束后,声发射活动性在较短的时间内恢复到稳定状态,且符合幂律衰减规律.“,”To investigate the progressive fracture processes around a tunnel triggered by static stress and dynamic disturbance, experiments and numerical simulations were performed. The results show that the spatial distributions of acoustic emission (AE) events become very different as lateral pressure coefficients change. The combined effect of static stress and dynamic disturbance causes the damage around the tunnel, and initial stress conditions control the damage morphology. The blast disturbance cannot fundamentally change the damaged area but will deepen the extent of damage and accelerate the failure speed. The more significant the difference between the vertical and horizontal stresses is, the higher the impact on the tunnel by the dynamic disturbance is. The AE activity recovers to a relatively stable state within a short time after the blast and conforms to power-law characteristics.
