禾洛山隧道是大丽铁路的控制性工程，存在涌水突泥等地质灾害。结合陡坡斜井突发涌水的工程实例，制定了“以堵为主，限量排放”的综合治理措施，在实践中摸索出适合现场的全断面预注浆的详细技术参数和方法，取得了良好的效果，为今后陡坡斜井处理突发涌水提供了借鉴经验。

 Heluoshan tunnel, one of the control works on DaliLijiang railway, has such geological disasters as water and mud gushing. The principle of "taking water sealing as dominant measure and releasing the water with limitation" is determined on basis of the actual situation of the sudden water gushing in one steep inclined shaft of Heluoshan tunnel. Detailed technical parameters and methods of fullface pregrouting are established and adopted and satisfactory effects are achieved. The details of the fullface pregrouting are presented in the paper, which can provide reference for similar projects in the future.
