通过原型观测试验获得了清江隔河岩大坝表孔、深孔闸门及坝体泄洪的实测数据。测试成果表明：在稳态工况下，表孔、深孔闸门运行平稳，大坝主体的振动很小。表孔闸门在3.3～7.0m开度时，出现了250 s左右的拍振现象,但不会影响表孔闸门的运行安全。深孔闸门在0.3～6.0m开度时,由于深孔闸门侧止水严重漏水,出现了强烈振动,应当引起足够重视。

During flood releasing from Geheyan Dam the flow in duced vibrations of the top opening gate and the bottom outlet gate in the dam were measured. The results showed that the two gates worked in perfect order, the vibration of the dam was very small. From 3.3mto 7.0 mopening a beat vibration occurred in the top opening gate, but it wasnt harmful to the gate. From 0.3mto 6.0m opening severe vibrations appeared in the bottom ou tlet gate caused by water ejecting from both sides of the gate. The side water tight seals should be renewed.
