为了较为准确地预测南水北调中线干线输水过程中的水量损失，通过分析渠道输水过程的主要损失水量计算方法，构建了相应的输水损失计算模型。利用京石段3次应急通水实测数据对预测模型进行了合理性验证，结果表明：利用输水损失模型计算得到的输水损失值与利用实测流量计算得到的输水损失值相差不大，精度满足要求，证明该模型是合理可行的。
為瞭較為準確地預測南水北調中線榦線輸水過程中的水量損失，通過分析渠道輸水過程的主要損失水量計算方法，構建瞭相應的輸水損失計算模型。利用京石段3次應急通水實測數據對預測模型進行瞭閤理性驗證，結果錶明：利用輸水損失模型計算得到的輸水損失值與利用實測流量計算得到的輸水損失值相差不大，精度滿足要求，證明該模型是閤理可行的。

In order to predict water loss during the delivery process of the South-to-North Water Diversion Middle Route Project, this paper built a water loss calculation model of main canal based on the analysis of existing methods of loss water. The rationality of water loss prediction model was tested by using the 3 times measured data of Beijing-Shijiazhuang reach emergency water supply. The results show that the water loss computed by water loss prediction model is correspond to the actual water loss and the calculation accuracy meets the precision requirement, which verifies the water loss prediction model is rational and feasible.
