长江干流上的 3 次截流即葛洲坝工程大江截流、三峡工程大江截流和三期导流明渠截流代表了当今世界大江大河截流的技术水平和发展方向。在分析 3 次截流施工特点并评价其技术水平的基础上，研究了河道截流施工的新技术、新进展及趋势，可为今后类似工程施工提供借鉴和参考。

The river closure constructions in three times on Yangtze River, including the main channel closure of the Gezhouba Project, the river closure of the Three Gorges Project and the diversion open channel closure of the Three Gorges Project, represent the latest technology and the development direction of river closure around the world. On the basis of analysis of the construction characteristics of the river closure in three times and evaluations of their technical levels, the author summarized the new construction technologies, latest progresses and development trends of river closure. These results may provide references for relative works in the future.
