摘　　要：鲁地拉水电站上游过水围堰采用土石—碾压混凝土混合过水围堰,该围堰建在深厚覆盖层上,具有大流量、高水头、长历时的过水特点。围堰建成后,经历3个汛期过水考验,运行良好。本文介绍该围堰的设计与运行情况,可供其他工程参考。The upstream overflow cofferdam for construction of Ludila Hydropower Station is an earth-rockfill-roller compacted concrete combined one, which is on a deep overburden layer and has the overflow characteristics of large flow rate, high head and long duration. After the completion, it experiences the overflows from three flood seasons with a better operation status. The design and operation of the cofferdam are described herein, so as to provide a reference for the other similar project.
