斜面升船机下游入水区水流流态及导航建筑体型的研究

Experimental Study on Flow Pattern in the Lower Ship Passage Area and the Navigation Structure for Inclined Ship Lift

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不区不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。

According to the hydraulic model test of navigation structures for inclined ship lift ofShiquan Hydropower Station,the flow pattern and velocity are investigated both in ship passage areawhere the ships are taken up or launched along ship lift railway and in the lower approach channel.Based on the original design,a kind of engineering measures to improve the flow pattersn and velocityis afforded in the paper and therefore guarantees ships to sail both in ship passage and in approachchannel safely and steadily.
