摘　　要：在隧道建造过程中,会遇到高压、富水、岩溶等有害地质条件,尤其是给浅埋偏压残坡体断层破碎岩溶隧道带来了涌水突泥和坍塌等事故危害。因此,极有必要对施工段内隧道涌水灾害采取一定的防治措施,依托龙(川)至怀(集)高速马口排隧道地质特点,结合周围环境条件,通过分析注浆方式的选择标准,研究马口排隧道注浆材料,确定了注浆加固圈厚度,从而选定了径向局部注浆堵水加固方案。In the process of tunnel construction, there are harmful geological conditions such as high pressure, rich water and karst, especially in the case of shallow-buried and partial-pressure residual fault faulted karst tunnels.Therefore, it is very necessary to take certain measures to deal with the gushing water disaster in the construction section. According to the geological characteristics of the Long （Chuan） to Huai （Ji） high-speed Maokou tunnel, combined with the surrounding environmental conditions, by analyzing the selection criteria of grouting, The grouting reinforcement of the grouting reinforcement is studied, and the reinforcement scheme of radial local grouting is selected.
