一元函数连积法用于水工建筑物流量定线研究

Study on The Unary Function Even Product Method Used for Hydraulic Structures′Determination of Discharge Data Relation Curve

目前用于水工建筑物流量定线的各种方法,都是基于水力学理论,由于没有摆脱模型函数的影响,定线精度一般不能达到最优化的目的。根据独立变量对"黑箱效应"的作用机理,将流量计算公式由模糊函数转化成各因子的一元函数连积形式,与模型函数相比,增加了可塑性和适应性。给出了各种流态的公式解析方法,并通过几类实例验证了该方法对提高流量定线精度的有效性。

The methods used for hydraulic structures′ determination of discharge data relation curve at present are based on the hydraulics theory,because of it is not to get rid of model function,the accuracy of the determination of data relation curve can′t reach optimized. According to the black-box effects which caused by the independent variable,the calculation formula of the discharge is transformed from ambiguity function into the one function product of each divisors,compare with the model function, it is increased plasticity and adaptibility. This paper gives analytical methods for each flow regime,and verified the effectiveness which increasing the precision of the determination of discharge data relation curve through some examples.
