摘　　要：以和邢铁路天河山隧道为例,在穿越高风险富水断层破碎带施工过程中,采用全断面超前帷幕注浆技术进行处理,有效控制隧道涌水,保证掘进过程安全。在此基础上,总结隧道在穿越高风险富水断层破碎带时的全断面超前帷幕注浆施工技术工艺和参数,提出隧道施工要重视超前地质预报、慎重选择止浆墙厚度等建议。Taking Tianheshan Tunnel of Heshun-Xingtai Railway as an example,in the construction process of crossing the high-risk water-rich fault fracture zone,the full section advanced curtain grouting technology is used for treatment,which effectively controls the water gushing in the tunnel and ensures the safety of the tunneling process.On this basis,the construction technology and parameters of full-section advanced curtain grouting when the tunnel passes through high-risk water-rich fault fracture zone are summarized,and the suggestions are put forward that the tunnel construction should pay attention to advanced geological prediction and carefully choose the thickness of grouting wall.
