以石泉水电站斜面升船机下游入水区及导航建筑为研究对象，通过模型试验，探讨了大坝下游斜面升船机入水区水流流态及流速分布情况。在设计方案的基础上，通过多次修改及放水试验，并在斜面升船机入水区采取了工程措施，才使升船机入水区流态平稳，流速大大降低，达到了行船设计要求。 Taking the downstream water intake area and navigational building of Ship lift of Shiquan hydropower station as the research object, the water flow pattern and velocity distribution in the water intake area of ​​the beveling ship downstream of the dam were discussed through model tests. On the basis of the design scheme, several modifications and water release tests were carried out and engineering measures were taken in the water intake area of ​​the bevel lift ship so that the flow regime of the lift ship entering the water area was stable and the flow rate was greatly reduced, thus meeting the ship design requirements.
