The DongHuanTuo mine transportation roadway meets the fault in the excavation. It is the first time to take the grouting to the tunnel at depth. It needs high technique and excavated method. Drilling arises spewing because of the unstable of rock. This article adopts the numerical simulation to analyse the causation. It is considered from the two aspects of mechanic and displacement, then it can direct the local work.

东欢坨矿-500运输大巷施工中,遇特大断层,首次将管棚注浆法运用到深部巷道的过断层施工中,由于断层破碎带极不稳定,在钻孔过程中出现了喷孔塌孔现象。本文针对这一现象,采用有限差分法分析发生喷孔的原因,从力学角度和位移场两方面来综合进行考虑,给现场施工和设计提供指导。

The dynamic disturbance may trigger the instable failure of rock mass when the high elastic strain energy is accumulated in the deep underground rock mass;and in turn it leads to occurrence of rockbursts.By considering the effect of different lateral pressure coefficients,the failure process of deep rock tunnels,which is triggered by dynamic disturbance,is simulated in order to clarify the failure mechanisms of tunnels at depth.The numerical results indicate that the triggering action of dynamic...

The dynamic disturbance may trigger the instable failure of rock mass when the high elastic strain energy is accumulated in the deep underground rock mass;and in turn it leads to occurrence of rockbursts.By considering the effect of different lateral pressure coefficients,the failure process of deep rock tunnels,which is triggered by dynamic disturbance,is simulated in order to clarify the failure mechanisms of tunnels at depth.The numerical results indicate that the triggering action of dynamic disturbances is closely pertinent to the static in-situ stress condition and the waveforms of the dynamic disturbance.In general,it brings about greater influences on the stability of underground tunnels with the increasing magnitude and with the prolonged duration of dynamic disturbance.Therefore,it is of theroetical and practical significance to investigate the effect of dynamic disturbance on the stability of underground tunnels.

处于深部的岩体内部积累了大量的弹性应变能,在外部动力扰动下这些能量以非常猛烈的方式释放,从而导致岩爆的发生。模拟不同侧压力系数条件下动态扰动触发深部巷道发生失稳破裂的整个过程,并揭示动态扰动触发巷道岩爆的力学机制。数值模拟结果表明,动态扰动对巷道变形与破裂的触发与地应力状态密切相关;动态扰动应力波的波形也是影响巷道破裂的重要因素,随着应力波幅值和应力波作用时间的加长,动态扰动给巷道稳定性带来的影响越大。因此,对动态扰动触发巷道破坏的研究具有非常重要的理论价值和现实意义。
