一、前言侧槽式溢洪道在我省小型水库中被广泛采用。侧槽式溢洪道的水力计算公式,都按动量原理推得,现在常用的不同形式的公式,其计算结果都很接近。1978年5月,当时省水利局曾以浙水农(78)4号文将我所编写的一份《中小型水库侧槽式溢洪道水力计算参考资料》发给地县水利部门参考。现将其中介绍过的原西南水工所的公式
I. Introduction The side channel spillway is widely used in small reservoirs in our province. The hydraulic formulas of the side channel spillway are deduced according to the principle of momentum. The commonly used formulas of different forms now have very close results. In 1978 May, when the Provincial Water Conservancy Bureau of Zhejiang Water Farmers (78) 4 text I wrote a “small and medium-sized reservoirs side channel spillway hydraulic calculation reference information” sent to the county water conservancy department reference. Now introduced the original Southwest Hydraulic Institute formula
