| 摘 要： | 通过物理模型试验和数学模型相结合的手段,对比分析了某低水头水利枢纽在运行中WES堰和改进后折线型实用堰的行洪能力和过沙能力.结果表明:2种堰型均能满足规范中平原地区的行洪能力要求,而WES堰的行洪能力略优于改进后折线型实用堰,但改进后折线型实用堰的堰面紊动强度较大、范围较广,能有效增强水流挟沙能力,易使泥沙起动,一定程...

| Abstract: | The flood discharge capacity and sediment transport capacity of WES weir and improved practical weir with polygonal line in a low-head hydro-junction are comparatively analyzed through physical model and mathematical model.The results indicate that the two types of weir both meet the requirements of norms and regulations for flood discharge in plain area.The discharge capacity of WES weir is better than that of the practical weir;whereas the improved practical weir is more beneficial for the normal operatio... |
