四零四厂取水枢纽是建立在多泥沙河流上的低坝引水工程 ,模型试验表明枢纽的整体布置设计合理 ,防沙冲沙效果明显。本文在试验成果的基础上分析探讨了该工程引水防沙设计较为成功的几个主要因素 The No.440 water intake project is a low-dam diversion project built on multi-silt rivers. The model tests show that the overall arrangement of the hub is reasonable and the effect of preventing sand and sediment flushing is obvious. Based on the experimental results, this paper analyzes and discusses several major factors that have led to the successful design of the project
