Flood discharge hole opening multi-layer asymmetric arrangement method suitable for high arch dams
The invention discloses a flood discharge hole opening multi-layer asymmetric arrangement method suitable for high arch dams, and belongs to the field of water conservancy and flood discharge architectures. The overlapping of trajectory nappes in the narrow space can be effectively avoided through the asymmetric arrangement of surface outlets and the asymmetric arrangement of deep hole planes. When the surface outlets are combined with the deep holes to discharge the flood, collision angles of each nappe in the air are reasonable, the surface outlet large or medium depression angle nappes collide with the deep hole small depression angle nappes, the surface outlet small depression angle nappes collide with the deep hole small jet angle nappes, the surface outlet small jet angle nappes collide with deep hole large jet angle nappes, the collision angles of the nappes in the air are in the range of 35-65 degrees, the collision angles are reasonable, and the nappes can be effectively dispersed.
本发明公开了一种适用于高拱坝的泄洪孔口多层不对称布置方法，属于水利泄洪建筑领域，本发明通过表孔不对称布置和深孔平面不对称布置能有效避免挑流水舌在狭窄的空间重叠。当表深孔联合泄洪时，各股水舌在空中的碰撞角合理，表孔大俯角或者中俯角水舌碰撞深孔小俯角水舌，表孔小俯角水舌碰撞深孔小挑角水舌，表孔小挑角水舌碰撞深孔大挑角水舌，水舌空中碰撞角度在35°‑65°范围内，碰撞角度合理，能有效分散水舌。
