水电站扩机工程进水口围堰拆除设计与施工——赞比亚卡里巴北岸水电站扩机项目

Design and Construction of Dismantlement of Intake Cofferdam in Extension Project of Hydropower Station:Zambia Kariba North Shore Hydropower Expansion Project

赞:赞比亚卡里巴北岸水电站始运营于1976年,扩机工程进水口围堰与老进水口的最近距离只有60m,与大坝的最近距离只有180m,围堰拆除是整个工程中的重大难点。在特大水库库容、深厚覆盖层以及深水位的情况下,对围堰进行了成功的爆破拆除,为类似工程提供了借鉴和参考。

The North Shore hydropower station in Kariba, Zambia was operated in 1976. The closest distance between the inlet cofferdam and the old intake of the expansion project is only 60 m. The closest distance to the dam is only 180 m. The demolition of the cofferdam is a major difficulty in the entire project. In the case of large reservoir capacity, deep overburden and deep water level, successful demolition of the cofferdam has provided reference for similar projects.
