| 摘要: |
| 【目的】合理划分多级枢纽自压滴灌系统田间管网工程建设规模,使工程综合成本费用最小化。【方法】以考虑工程使用年限的单位面积综合成本费用最低为目标,以管网布置、管径、流量、压力等为约束条件,建立了多级枢纽自压滴灌系统田间管网工程建设规模优化数学模型,并采用原子搜索优化算法进行求解。【结果】以新疆某两级枢纽自压滴灌工程为例,采用该方法对其田间管网工程规模进行优化,结果表明当田间管网工程规模为89 hm2时,单位面积综合成本费用最低,并通过计算分析得出田间管网工程规模为74 hm2至98 hm2范围时较优。同时,计算分析不同灌水器间距、毛管间距及灌水器设计流量下的最优工程规模,结果表明三者组合方式不同最优规模不同,对应的田间长宽比范围为1.00-1.30,且最优规模对应的单位面积综合成本费用随着灌水器间距或毛管间距的增大而减小,随着灌水器设计流量的增大而增大。【结论】该方法可对多级枢纽自压滴灌系统的田间管网工程规模进行优化,另外,原子搜索优化算法稳定,计算速度较快,计算精度高,该方法对自压滴灌系统的优化设计具有一定的应用价值。 |

| Abstract: |
| 【Objective】The objective is to reasonably divide the field pipe network construction scale of multi-level gravity drip irrigation system, which minimizes the comprehensive cost.【Method】Taking the lowest comprehensive cost per unit area considering the service life of the project as the objective function and taking the pipe network layout, pipe diameter, flow and pressure as constraints, the construction scale optimization mathematical model of field pipe network project of multi-level gravity drip irrigation system was established and solved by atom search optimization (ASO).【Result】Taking the gravity two-level drip irrigation project of Xinjiang as an example, this method was used to optimize its field pipe network construction scale. The results showd that when the field pipe network engineering is 89 hm2, the total cost of comprehensive cost per unit area is the lowest, and it is excellent when the construction scale is 74 hm2 to 101 hm2. At the same time, the optimal project scale under different emitter spacing, different capillary spacing and different design flow of emitter was calculated and analyzed. The results showed that the combination of the three is different, the optimal scale is different, the corresponding length-width ratio of field ranges from 1.00 to 1.30, and the comprehensive cost per unit area of the optimal scale decreases with the increase of emitter spacing or capillary spacing, and increases with the increase of emitter design flow.【Conclusion】This method can be optimized for the construction scale of field pipe network project of multi-level gravity drip irrigation system. In addition, the atom search optimization algorithm is stable, and its calculation speed is fast and the calculated accuracy is high. The proposed method has a certain value of the optimization design of the gravity drip irrigation network system. |
