象山县水利局谢世安工程师以动量定律为依据,导出了以侧槽水深hn为未知数的一元二次方程,可用求根方式解方程,逐段算出侧槽水面线,简化了计算工作,且精度达到设计要求。用《水利水电技术》1983年第7期肖广源文章的算例进行验证,新方法计算成果与现行几种公式的结果十分接近,仅差1%左右。但该法比图解法可提高工效两倍左右, Based on the law of momentum, Xie Shian, an engineer from Xiangshui County Water Conservancy Bureau, derived a univariate quadratic equation with the water depth hn as the unknowns in the side channel. The roots can be used to solve the equations and calculate the side channel water surface line by section to simplify the calculation. The accuracy Meet the design requirements With “water conservancy and hydropower technology” in 1983 seventh Xiao Guangyuan article examples to verify that the results of the new method and the results of several existing formulas is very close, only about 1% difference. However, the law than the graphic method can improve ergonomics about twice,
