摘要
在隧道施工过程中,因隐伏于岩体中的含水构造系统被揭露破坏,很可能导致开挖临空面与导水通道进行连通,从而发生突水突泥灾害。通过建立充填介质滑移失稳力学模型并利用有限差分模拟软件模拟岩溶管道在不同水压力影响下隧道发生突水突泥的可能性,研究了复杂地质条件下隧道突水突泥的致灾机理。结果可供隧道施工参考。
In tunnel construction, the excavation of the surface and the water guide channel are most likely to be connected because the hidden water-bearing structural system is inevitably revealed and destroyed, thus causing water inrush and mud outburst in the tunnel.The possibility of such disaster was predicted by establishing the sliding instability mechanics model of filling medium and using finite difference simulation software to simulate Karst pipeline under different water pressure.The catastrophic mechanism of water inrush and mud outburst in complex area was studied.The results can provide reference for tunnel construction.
