摘要
该文阐述三峡明渠导流的模型试验研究成果,含明渠池流能力,过流断面形式,渠道进口纵向堰头部形状,河岸保护,航道河段整治及船只上行航线等。并对原型泄洪运行中尤其是1998年大洪水作了观测,包括明渠水流情况,两岸水位,明渠底面冲淤变化,围堰护坡淘刷及船只航行等。
This article introduces the model test achievement of Three Gorges Project open channel diversion, including open channel discharge capacity, discharge section configuration, longitudinal cofferdam head configuration of channel intake, river bank protection , sea route river section renovation and up - sail sea route etc. In the article prototype discharge operation achievement (flood operation in 1998 specially) is also introduced, including open channel water - flow condition, water level of both river banks, open channel bottom section eroding and silt changes, slope - protector erosion of cofferdam and ship navigation, etc.
