特长砂岩地质隧道穿越断层的富水破碎带反坡排水施工技术研究

Study on the Construction Technology of Reverse Slope Drainage for Tunnel Passing Through the Water-Rich Fracture Zone of the Fault in Extra-Long Sandstone Geology

在隧道穿越断层富水破碎带的施工过程中,通常会采用反坡排水施工技术预防涌水突泥事故的发生。论文结合某公路隧道工程实例,对特长砂岩地质隧道穿越断层富水破碎带施工中的反坡排水技术应用进行研究,为相似工程提供一些参考。

In the construction process of tunnel crossing the fault water-rich crushing zone,reverse slope drainage construction technology is usually adopted to prevent the occurrence of mud gushing and water gushing accidents.Combined with a highway tunnel project,this paper studies the construction technology of reverse slope drainage for tunnel passing through the water-rich fracture zone of the fault in extra-long sandstone geology,and provides some references.
