摘　　要：隧洞涌水是TBM施工中主要应对的安全风险和施工难点。结合桂中治旱乐滩水库引水灌区一期工程北干渠窑瓦~六浪隧洞工程实例,论述了TBM施工隧洞内在刀盘前方采取全断面超前分段注浆处理的方法与过程,并分析了处理效果。Water gushing is the major safety risk and problem of TBM construction. Quyaowa-Liulang tunnel is one of the 1 st-stage works of Letan Reservoir Irrigation Project. Taking the construction of this tunnel as example, the authors discuss the method and process of full-section advance sectional grouting in front of the drill during TBM construction, and analyze the treatment effects.
