本文根据校正因数法的基本原理,采用浮动多项式选配水位与稳定流量的关系方程和水位与校正因数的关系方程,以模拟计算的流量与实测流量相对误差的平方和最小为目标准则,分析了约束条件,建立了洪水绳套曲线的模拟模型;提出了用正多面体法对模型参数进行求解优化。实例验证结果表明,该法能有效地模拟受洪水涨落影响的水位流量关系绳套曲线,且对受其它因素影响的流量资料整编具有一定的指导意义。
In this paper, according to the basic principle of the correction factor method, the relational equation between the water level and the steady flow of the floating polynomial and the equation of the water level and the correction factor are adopted. Taking the minimum square sum of the simulated flow and the measured flow as the objective criterion, The simulation model of the curve of flood cages is established and the optimization and optimization of model parameters by using the method of regular polyhedron are proposed. Experimental results show that the proposed method can effectively simulate the relationship between the water level and the flow rate affected by flood fluctuations, and is of guiding significance to the reorganization of the flow data affected by other factors.
