摘要
为了更好地拟合调洪演算当中的水位库容曲线、水位泄流能力曲线,提高调洪计算的精度,尝试采用三次样条插值函数进行入库洪水的调洪演算。在分析三次样条插值函数与调洪演算结合的基础上,通过delphi平台编写了调洪演算程序。实例计算结果证明,三次样条插值函数在调洪演算中是可行的。
In order to better fit the curves of water level-storage and water level-discharge capacity in flood routing, and improve the accuracy of flood routing, the application of cubic spline interpolation function in flood routing of inflow flood is studied herein. Based on the analysis of the combination of cubic spline interpolation function and flood routing, the flood routing procedures are written by Delphi platform. The case calculation shows that the cubic spline interpolation function can be used in flood routing.
