以滴灌灌水器平均流量与设计流量的差值为目标函数，将支管末端节点的压力水头作为决策变量，应用二分法与退步法进行毛管和支管的水力计算，建立微灌灌水小区整体水力设计的遗传算法模型。仿真结果表明，模型与算法具有很高的求解效率、计算精度以及良好的通用性和实用价值。在进行灌水小区水力设计的同时，还能够得到支管和毛管的流量、压力分布，以及灌水器平均流量、最大流量、最小流量等特征值及其孔口位置，确定压力偏差、流量偏差、灌水均匀度等灌水质量控制指标。可适用于非均匀坡、变管径、变间距等坡地微灌灌水小区的水力计算与设计，也可用来对已设计或铺设好的灌水小区进行校核与评价。
- Abstract:

Taking the difference value between the average flow and design flow of drip irrigation emitter as the objective function, the pressure head of the end node of the branch as the decision variable, the hydraulic calculation of capillary and branch pipes was carried out by using dichotomy and regression methods, a genetic algorithm model of the whole hydraulic des ign of micro irrigation district was established. The simulation results showed that the model and algorithm had high solving efficiency, computational accuracy, good versatility and practical value. By doing hydraulic design on the irrigation plot, we could get branch and capillary flow, pressure distribution, characteristic values as emitter average flow, maximum flow and minimum flow, and the position of the orifice, to determine the irrigation water quality control indexes such as pressure deviation, the flow deviation, uniformity. The utility model could be applied to the hydraulic calculation and design of the sloping irrigation district with uneven slope, variable pipe diameter, variable spacing, etc., and could also be used in checking and evaluating the irrigation plots which had been designed or paved.
