摘要
基于VB运行环境,采用逆流递推法对支毛管总水头损失进行逐段编程计算,用以求解灌水小区的流量偏差率。同时利用田间小区试验测定支毛管上各孔流量和压力,对该软件的适用性进行验证。结果表明,各个灌水小区支管毛管各观测点压力水头的模拟值与实测值标准差均小于0.13m,均值误差的绝对值均小于10%,模拟效果较好,可以应用于灌水小区流量偏差率的模拟计算。
Based on the operating environment of VB,the countercurrent recursive method was used to calculate the total head loss of the branch and capillary,which might be be used to solve the flow deviation rate of the irrigation district.At the same time,the application of the software was verified by measuring the flow and pressure of the branch pipe by field experiments.The results showed that the RMSE of simulated and measured values of pressure at each observation point of each irrigation district were all less than0.13 m,and the absolute value of ME was less than 10%.The simulation results were good and could be applied to the simulation calculation of flow rate deviation rate in irrigation district.
