摘要
该文介绍了目前水利工程中明渠流量测量的主要手段和方法,分析了各种方法的适用范围及优劣.重点介绍了目前明渠流量计算中一些常用的研究方法,如回归法、量纲分析法、深度平均法、求解圣维南方程法、数学建模法以及新兴的神经元网络方法等,同时归纳总结了一些现有的典型的明渠流量计算公式,分析了优缺点.最后对研究的现状提出了自己的看法,以供水文工作者借鉴.
This paper introduces methods of calculation for open channel discharge in the current hydraulic engineering. The application areas, and the advantages and disadvantages are discussed. Some calculation methods for open channel discharge are also given. These include the regression method, dimensional analysis method, averagingdepth method, SaintVenant equations method, mathematics modeling method, and the rising neural network method, etc. The paper also summarizes some typical formulae on open channel discharge, and analyzes respective advantages and disadvantages. Some opinions are presented for the reference of hydrologists.
