龚嘴水电站#15底孔弧门支承铰失效的影响研究

Failure of Bearing Hinge Influencing on Operation of Deep-outlet Radial Gate of Gongzui Hydropower Station

结合龚嘴水电站 # 15弧形闸门支承铰转轴失效的实际状况 ,计算了由此引起的弧门附加启门力和附加应力 ,并分析附加启门力和附加应力对弧门正常启闭和弧门整体强度的影响 ,为弧门的技术改造和安全运行提供参考。

Aiming at the practical case that the bearing hinge of radial gate failed to rotate under the normal loads, the additional lifting force and secondary stresses of the gate are calculated to evaluate the influence on the strength and operating reliability of the gate.
