摘　　要：长距离泵输水工程管径选择合理与否直接影响工程投资和运行费用。采用费用现值法,考虑工程运行初期和远期输水流量不同、泵站运行方案不同、水泵工作扬程和水泵机组效率不同以及我国实行两部制电价等因素,探讨长距离泵输水工程经济管径的确定问题。以陕西某长距离泵输水管道工程为例,介绍了DN450,DN500,DN600和DN700等4种管径的费用现值计算,以及输水管道经济管径的确定过程,可供类似长距离泵输水工程经济管径选择参考。Reasonable selection of pipe diameter of long-distance pumping water conveyance project greatly affects the investment and operation costs. Using the costs present value method,taking into account of the different water delivery volumes during the initial and long-term operation periods,the different pump station operation plans,the different the pump work heads and water pump efficiencys,and the two-part electricity prices,the economic pipe diameter for of long-distance pumping water conveyance project was determined. The project in Shanxi was taken as an example,the costs present value calculation diameter determination processes of pipe diameter for 4 types of pipe diameter,i. e,DN450,DN500,DN600 and DN700,and the diameter determination processes of economic pipe diameter were introduced. It can provide references for the selection of economic pipe diameter of similar long-distance pumping water conveyance projects.
