| 中文摘要: |
| 在泄洪洞事故闸门动水下门过程中，洞内可能产生巨大的噪音和强烈的振动。为了保证孔板泄洪洞的运行安全，在理论分析的基础上，对孔板泄洪洞事故闸门动水下门过程进行实验研究。试验中，量测了泄洪洞沿程的脉动压力，事故闸门门井进口的风速等，并观测了孔板洞内的流态和分析了中闸室噪音和振动的成因并提出了相应的措施。 |
| 英文摘要: |
| In the process of emergency gate shutting in an orifice tunnel, big noise and strong vibration would be observed within the mid gate-chamber. In an experimental study, the pressure fluctuation along the tunnel and the wind velocity at the gate entrance were measured. The flow pattern in the orifice tunnel was observed. The reasons of the noise and vibration were analyzed and some countermeasures were proposed. |
