【Abstract】 The impervious technique of high-pressure gunite applied to stage I embankment cofferdam of the Three Gorges Project was introduced comprehensively. A detailed account of its construction arrangement, parameters, procedure and method was provided. The fact that the impervious technique of high-pressure gunite is feasible for the completely decomposed granite in the Three Gorges was validated by the project practice, and the imperviousness can be guaranteed. The successful application of this technique can be a reference to other projects.更多还原
