汉泉隧道突水突泥处治措施

Treatment of Water and Mud Sudden Inrush in Hanquan Tunnel

结合汉泉隧道施工期间出现的突水突泥情况,在物探、钻探、地表调查的基础上,对隧道发生突水突泥的原因进行分析.采用排水降压、超前管棚、洞周注浆、抗水压衬砌的综合处治措施,储水带破碎围岩得到有效改善和加强,围岩变形和涌水得到有效控制,隧道安全、顺利、快速地通过突水突泥段,可为类似隧道勘察、设计及突水突泥应急处治提供一定的参考.

Combined with the water and mud sudden inrush During the process of the construction in Hanquan tunnel,the causes of the water and mud sudden inrush are analyzed on the basis of geophysical exploration,drilling and surface investigation.the comprechensive treatment scheme of“drainage and pressure lowering,advanced pipe shed,perimeter grouting,water pressure resistance lining”,the deformation of surrounding rock and water gushing are effectively controlled,Tunnel construction safely,smoothly and quickly through the water and mud sudden inrush section.It has certain reference significance for tunnel survey,design and emergency treatment of water and mud sudden inrush.
