摘要
水电站引航道隔流堤采用透空型式,虽可调整航道口门区的流速分布,改善不良流态,但也会对引航道停泊段的水流条件产生不利影响。结合构皮滩水电站工程实际,采用水工模型试验和船模试验的方法,对构皮滩水电站下游引航道隔流堤不同透空形式的水力学特性进行了研究。结果表明:在透水通道平面角度45°,透水通道9个,透水面积75.6 m2时,下游引航道停泊段及口门区的水流条件均满足通航要求。对类似工程具有参考借鉴作用。
The hollow-type separation levee of approach channel in the hydropower station will cause an adverse effect on the flow conditions at the parking section of approach channel even if it can adjust the velocity distribution of the channel entrance area and improve the poor flow pattern.Therefore,the hydraulic characteristics with different hollow-type separation levee of downstream approach channel in downstream of Goupitan Hydropower Station are studied by adopting the hydraulic model test and ship model test,with the consideration of engineering practice of the station.The result shows that the flow conditions of the parking section of downstream approach channel and the entrance area can meet navigation requirements by adopting the plane angle of 45°,9 permeable channels with the total permeable area of 75.6 m2.
