Medium and low earth and rockfill dam overtopping protection drainage structure and design method thereof
The overtopping protection, drainage and drainage structure of the medium-low earth and rockfill dam comprises a dam crest drainage and drainage structure, a downstream slope surface drainage and drainage structure and a dam foot drainage and energy dissipation structure which are sequentially arranged from top to bottom along the cross section of the dam. Wherein the dam crest drainage structure is used for collecting part of overtopping water flow; the downstream slope surface drainage structure is used for receiving overtopped water flow collected by the dam crest drainage structure and further guiding, collecting and dissipating energy of the water flow overtopped to the downstream slope surface; and the dam foot drainage and energy dissipation structure is used for dissipating and discharging the energy of the incoming flow of the downstream slope surface drainage and drainage structure. The method comprehensively considers concentrated guiding, discharging and energy dissipation of overtopping washing water flow, and has a better overtopping protection effect.
本发明公开了一种中低土石坝漫顶防护引流排水结构及其设计方法，所述中低土石坝漫顶防护引流排水结构包括沿大坝横断面自上而下依次设置的坝顶引流排水结构、下游坡坡面引流排水结构和坝脚排水消能结构，其中坝顶引流排水结构用于收束部分漫顶水流；下游坡坡面引流排水结构用于承接所述坝顶引流排水结构收束的漫顶水流，并进一步对漫至下游坡坡面上的水流进行引导、收集、消能；坝脚排水消能结构用于对所述下游坡坡面引流排水结构来流进行消能并排出。本发明综合考虑了漫顶冲刷水流的集中引导、排放与消能，具有更好的漫顶防护效果。
