摘　　要：当前的隧道涌水突泥处理结构多为单向,处理范围受限制,导致隧道渗水率提升,为此,文中对特长隧道施工中涌水突泥处理技术的设计与验证进行研究。根据当前的测定需求及标准,进行地表处理及洞内突泥清理,实现隧道排水。采用多层级方式,打破涌水突泥处理范围限制,完成多层级导坑结构加固,对洞身填充注浆处理,设置衬砌、搭建支护结构,进行隧道清理及后期维护。结果表明,在选定的7个测试周期,该隧道渗水率均被控制在2.5%以下,说明该技术对涌水突泥的处理效果更佳,针对性更强,具有实际应用价值。In the current tunnel construction,the treatment structure of the treatment is mostly unidirectional,and the scope of the treatment is limited,leading to the increase of the tunnel seepage rate.Therefore,the design and verification study of the treatment technology in the construction of special tunnel is proposed.According to current measurement requirements and standards.On this basis,the surface treatment and mud cleaning in the hole are carried out to realize the tunnel drainage.The multi-level method is adopted to break the limit of the reinforcement of the multi-level guide pit structure,the hole flling and grouting treatment is completed,the lining and the support structure are set up,and the treatment is completed through the tunnel cleaning and later maintenance.The example analysis results show that for the selected 7 test cycles,the water seepage rate of the tunnel is better controlled below 2.5%,indicating that in the current treatment form,the treatment effect of water rush mud is better,more targeted,and has practical application value.
