| 摘 要： | 提出一种平底侧收缩堰作为灌溉渠中的新型量水堰，以代替通用的薄壁堰，并对这种堰的水流特征进行了分析与初步的试验研究。这种堰的特点是构造简单，水位落差小，可在多沙渠槽中应用，而不会在堰前产生泥沙淤积。

| Abstract: | This paper puts forward a kind of flatbottomed side contracted weir.As a new type of measuring weir,it can substitute for the thinplate weir that generally used in irrigation canal.The characteristics of the weir are simple in construction,small in drop of water level and not producing silt accumulation in front of the weir.The paper has analysed the water characteristics of the weir and has conducted the primary experimental research. |
