摘　　要：结合亚碧罗水电站施工导流模型试验,针对在试验中出现的试验结果中导流洞的流量系数比计算值偏大的问题,实测了亚碧罗施工导流模型试验中的导流洞出口η值,发现由实测值推出的流量系数更加符合以前的试验经验、更加接近计算结果。Combining with the model test of Yabiluo Hydropower Station＇s diversion and in view of the problem arising in the test that the flow coefficient of the diversion tunnel is bigger than calculated values,the value η of the diversion tunnel in Yabiluo Hydropower Station＇s diversion model is measured,and it is found that the value derived by the measured water depth（hp） is more in accordance with the test experience and much closer to the calculation results.
