摘　　要：高原某铁路隧道穿越诸多活动断裂带,通过对隧道穿越活动断裂带处的突泥、涌水工况处治施工技术进行研究,将超前地质预报作为一道重要工序纳入日常管理,采用多种预报手段相互印证,综合研判,真正做到“围岩为本,地质先行”,采用长短结合泄水孔并充分利用平导施作横向泄水孔实现探水、泄水,根据泄水情况动态调整工程措施,采用加强超前支护、轻量化超前注浆、帷幕超前注浆等措施,并验证注浆效果,保证后续施工安全,颇具工程借鉴价值。A railway tunnel on the plateau passes through many active fault zones.Through the research on the treatment and construction technology of the mud and water inrush conditions at the active fault zone where the tunnel passes through,the advanced geological prediction is included in the daily management as an important process,and a variety of prediction methods are used to confirm each other,and comprehensive research and judgment are made to truly achieve the goal of "surrounding rock first,geology first",and the combination of long and short drainage holes and the full use of horizontal drainage facilities as horizontal drainage holes to achieve water exploration.For water release,the engineering measures shall be dynamically adjusted according to the water release situation.Measures such as strengthening advance support,lightweight advance grouting and curtain advance grouting shall be adopted,and the grouting effect shall be verified to ensure the follow-up construction safety,which is of great engineering reference value.
