摘　　要：在简要介绍南水北调中线水源工程丹江口大坝加高工程概况的基础上,针对大坝加高中新老混凝土结合面新增人工键槽施工的关键技术,分析了现有施工方法及存在问题,研究并提出了新的锯割静裂法施工法。最后,给出了新方法的工程实际应用情况及成效。On the basis of brief introduction of Danjiangkou Dam Extension Project which is in the Middle Route water resources project of the South-to-North Water Diversion, the present construction methods and existing problems about key technology of increased artificial concrete keyway of jointing surface between new concrete and existing concrete are analyzed, and a new construction method by saw-cutting and static crack for construction of concrete keyway is researched. Actual application and results of the new construction method are presented.
