摘　　要：针对富水软弱带突泥涌水工程,通过理论分析和现场试验,对该隧道突泥涌水成因、处治技术进行研究,得出突泥涌水灾害的形成主要受地质条件和施工作业影响。对于一定规模的突泥涌水灾害,泵送混凝土、注浆改良松散体,释放水压力,超前大管棚,超前注浆小导管等措施有较好的处治效果。总结出“控制能量积蓄,合理释放能量,增强防突能力”的突泥涌水处治技术原则,在某隧道突泥涌水处治实践中取得良好效果。Based on the theoretical analysis and on-site tests,the causes and treatment technology of mud and water inrush of a tunnel in the water-rich soft zone of the mud and water inrush project are studied.It is concluded that the formation of mud and water inrush disasters is mainly influenced by geological conditions and construction operation.For a certain scale of mud and water inrush disasters,the measures such as pumping concrete,grouting to improve loose bodies,releasing water pressure,advancing large pipe sheds,and advancing grouting small conduits have good treatment effects.The technical principles of"controlling energy accumulation,reasonably releasing energy,and enhancing anti-outburst ability"for the mud and water inrush treatment are summarized,so as to achieve good results in the practice of mud and water inrush treatment of a tunnel.
