Abstract： Water plugging by advanced curtain grouting is an important means to ensure the safe construction of water-rich surrounding rock of the tunnel. Taking the ice-water deposition section of a tunnel of Sichuan-Tibet Railway as an example， this paper introduces in detail the overall construction method and concrete operation of leading curtain grouting water plugging construction， and simply evaluates the grouting effect. Thus， some suggestions on the construction technology of advanced curtain grouting are put forward， in order to provide some reference and successful experience for the construction of similar projects.

Keywords： tunnel; ice-water deposit; advanced curtain grouting; water plugging; railway construction
