汕头市大龙溪一级水库溢洪道除险加固工程水工模型试验研究

Hydraulic Model Experiment Study for Spillway of Dalong Primary Reservoir in Shantao

针对大龙溪一级水库溢洪道下游地形特殊以及由此带来的下游消能问题,通过多方案的比较试验研究,提出适合工程实际的“斜向高低挑流鼻坎”的消能方案。该方案较好地适应了消能区的特殊地形,较好地解决了溢洪道下游的消能防冲问题,试验研究成果可供同类型工程设计和运行参考。

According to the special topography of spillway downstream of Dalong primary reservoir and the problem to the energy dissipation of downstream, the authors put forward the energy dissipation method with 'tipsy height and low on defection bucket' to solve the practical engineering problem after comparing with a lot of methods. This method could be applied to energy dissipation area with special topography, and could be used to solve the erosion control problem in spillway downstream very well. It could be applied to similar projects.
