摘　　要：对已有的船闸出水孔段廊道的模型试验及原型观测资料进行了对比分析后 ,指出该段廊道的阻力系数 ,除沿程摩阻损失可按糙率及雷诺数进行校正外 ,其余均属局部阻力性质 .在廊道雷诺数达到 5× 1 0 4 后 。In this paper, the head loss coefficient of lock culvert manifold is discussed. A comparison between the existing model tests and related prototype observations is conducted. It shows that for culvert manifold, except the friction loss which can be corrected by culvert roughness and Reynold Number Re , the others possess local head loss characters and are constant. When Re in the culvert reaches 5×10 4, there is no scale effect further.
