摘要
黄河小浪底调水调沙是治黄管理的重要措施。通过对实测流量和排沙量变化过程的分析,依据插值和拟合数学理论,结合matlab得到排沙量与时间、流量的函数关系式,并进行数值分析验证,对调水调沙试验的效果进行了理论分析。
The water and sediment regulation is an important countermeasure of managing Yellow River. By analyzing the changing process of water and sand discharge , and using the interpolation and the fitting mathematic theory, based on matlab software, the fucntion of sand discharge, time and tonnage is obtained. And numerical integration is calculated to get total sand discharge. The result of imitating the data obtained shows that it is important for analyzing and predicting the experiment of water and sand adjustment.
