摘要
通过理论计算和模型试验,对东湖水电站引水隧洞工程清河分水口分流堰及侧堰过流能力进行对比分析,同时验证了侧堰泄槽的过流能力:分流堰过流能力研究按照自由出流及下游水位225.68 m两种工况考虑,侧堰过流能力研究按照闸门全关闭及局部开启两种工况考虑。研究结果表明,分流堰、侧堰以及泄槽的过流能力满足工程需求,设计型式合理可行,可应用于本工程,同时也为其他类似工程的设计提供参考。
Through theoretical calculation and model test,the flowing capacities of both the dividing weir and the side weir of Qinghekou Dividing Gate for the diversion tunnel of Donghu Hydropower Satation are comparatively analyzed herein,meanwhile,the discharge chute for the side weir is certified as well; i. e. the flowing capacity of the dividing weir is studied under the consideration of the conditions of free flow and the downstream water level of 225. 68 m and the flowing capacity of the side weir is studied under the consideration of full close and part open of the gate. The study result shows that the flowing capacities of the dividing weir,side weir and discharge chute can meet the demand of this project and the designed pattern is reasonable and feasible,thus cannot only be applied to this project,but also can provide a reference for the similar project concerned.
