摘要
高水头动水闭门试验由于水力学复杂、不定因素较多、甚至可能引起次生灾害,一直行业内较忌惮的工作。小湾水电站放空底孔事故链轮闸门经过模型试验研究及参建各方的努力,成功完成了设计水头下的动水闭门试验,对该闸门的模型试验、原型试验情况进行了详细介绍及分析,并就两者进行了对比,为今后同类型高水头闸门的设计提供借鉴。
The hydrodynamic closing test of gate under high water head is always a problem in hydropower industry because of complex hydraulics, many uncertainties and possible secondary disasters. The actual hydrodynamic closing test of emergency caterpillar gate in emptying bottom outlet of Xiaowan Hydropower Station under designed operation head is successfully completed after model experimental tests. The results of model test and prototype test are analyzed and compared herein. The results will provide references for the design of gates with same type and higher operating head.
