Abstract: Treating leakage through dam structure joints and cracks was limited by technology, equipment and materials in the past, most need passively repairing at downstream face, repairing at upstream face is not only extremely difficult but also spend much money and time. In this paper, authors introduced a case of repairing at upstream slope along with its working plan and construction technique.?

摘要： 大坝结构缝、裂缝漏水问题较为常见，以往因技术、设备、材料的限制,多数在背水面被动地进行处理，迎水面水下处理相当困难或处理效果事倍功半。本文通过某大坝结构缝迎水面水下处理施工实例，介绍水下处理工作方案与施工工艺等经验，为类似工程水下处理提供借鉴。
