摘要:
孔流与堰流同时存在时,分流点的位置是区分2种流态的重要指标。为得到分流点竖向位置,以便更好地区分2种流态,本文采用物理模型实验,通过不同参数的分析比较,提出了分流点竖向位置的数学关系表达式。基于水力学基本理论,采用雷利法给出影响分流点竖向位置的无因参数,分析各参数与分流点竖向位置的关系并对参数的敏感性进行比较;基于最小二乘法,建立5种不同参数的分流点竖向位置的数学模型,通过统计指标的比较得到预测分流点竖向位置的最优模型;对最优模型进行检验并与实验值进行比较,得到该模型可用来精确地描述分流点的竖向位置。本文提供的分流点竖向位置计算表达式可用于实际工程并为相关水利工程的泄流能力研究提供依据。
