中文摘要：
南水北调中线全线自流，各渠段水头分配很严格，穿黄隧洞作为路线上的关键工程，正确估算其水头损失非常重要。文章利用1：29．17的正态模型对穿黄隧洞的沿程水头损失系数λ与Re的关系进行了研究；对穿黄隧洞的总水头损失进行了测量，并与计算结果进行比较。所获得的设计与校核流量下的总水头损失值，可供工程设计、校核参考。
英文摘要：
In the middle Route Project （MRP） for South-to-North Water Diversion the water will flow automatically, and water head is very small for every channel. So it is very important for tunnel crossing Yellow River,a critical path in MRP, to estimate its head loss correctly.Based on the undistorted model with scale I ~ 29. 17, the paper studied the relation of λ and Re in the tunnel crossing Yellow River, and conducted the total head loss of the tunnel. Furthermore, it compared the calculation with test result. The conclusion can he referred by the design and verification of MRP.
