摘　　要：针对富水风化花岗岩隧道突水突泥灾害频发、危害严重的难题,以广西均昌隧道突水突泥灾害防治为例,通过分析隧道历次突水突泥灾害特征,提出富水风化花岗岩隧道突水突泥灾害防治总体原则,综合室内试验与现场试验,建立了以浆液复合、注浆工艺复合、注浆压力动态调控为核心的动态信息化帷幕注浆技术,并形成了以检查孔观察法、检查孔取芯法、涌水量分析法及检查孔P-Q-t曲线法对帷幕注浆效果进行综合评价的方法,成功解决均昌隧道突水突泥灾害防治技术难题,研究成果对类似地质条件的隧道建设具有重要的参考价值。Water and mud inrush disaster occurs frequently in weathered granite regions with abundant water,which does tremendous harm to the construction of tunnels and surrounding environment.Combining with the treatment practice of water and mud inrush disaster of Junchang tunnel in Guangxi Zhuang Autonomous Region,the treatment princi-ple of water and mud inrush disaster was determined firstly based on the characteristic analysis of water and mud inrush disasters.The composite curtain grouting technique was established for sealing groundwater and reinforcing the surrounding rock,based on the laboratory and field tests.And the comprehensive evaluation method of grouting effect was proposed in order to evaluate the implementation results of curtain grouting work.The proposed treatment technology had successfully solved the water and mud inrush disaster in Junchang tunnel.And the research results could provide reference and guide for the prevention and treatment of water and mud inrush disaster in similar geological conditions.
