本文提出了建立长距离输水管线数学模型进行管线模糊优化设计的方法,就系统建模过程中涉及的长距离输水管线的水力计算、结构计算、水力瞬变的计算、管材选择、管线的自控理论等几个关键技术问题进行了探讨,指出在我国制定长距离输水管线设计与施工国家标准已迫在眉睫,并建议在我国长距离输水管道中应尽快应用SCADA系统。 This paper proposes a method for establishing a mathematical model of long-distance water pipelines for pipeline fuzzy optimization design, including hydraulic calculations, structural calculations, hydraulic transient calculations, pipe selection, and pipelines for long-distance water pipelines involved in the system modeling process. Some key technical issues such as the theory of automatic control were discussed. It was pointed out that the establishment of a national standard for the design and construction of long distance water transmission pipelines in China is imminent, and it is recommended that the SCADA system should be applied as soon as possible in China’s long distance water transmission pipelines.
