| 摘 要： | 试验研究了三峡工程运行至50+4a和70+6a汛期电站日调节非恒定流对上游引航道口门区水流条件的影响。结果表明,通航水流条件主要控制因素为口门区的横流、船闸前的波高,在日调节过程中所要求的日调节流量下,均难以满足通航水流标准要求。对此,提出了改善引航道口门区通航水流条件的几种不同措施。

Influence of Daily Regulation of the Three-gorge Power Station on Navigation Flow Conditions During Flood Period and Its Improving Measures |
| |
| Abstract: | The influence of unconstant flow due to daily regulation of the power plant during flood seasons on flow conditions in the entrance area of the usptream approach is tested,in case the Three-gorge Project has run 50+4 years and 70+6 years.The results show that the cross current in the entrance area and the wave height before the lock are the main factors to the flow condition.However,it's difficult for them to meet the demands of navigational flow under the required discharge during the daily regulation.Therefore,various designs are proposed for improving navigational conditions in the area. |
