峡江水利枢纽位于“S”形弯道内,引航道上、下游口门区通航水流条件非常复杂。通过物理模型试验研究了引航道口门区通航水流条件,并给出了优化布置方案。结果表明:通过调整引航道中心线位置、缩小引航道中心线与河道主流流向交角,并适当开挖局部高地,有效地改善了上游引航道通航水流条件;下游引航道通航水流条件则主要以外扩式底部透空导流墙整流措施来改善。
峽江水利樞紐位于“S”形彎道內,引航道上、下遊口門區通航水流條件非常複雜。通過物理模型試驗研究瞭引航道口門區通航水流條件,併給齣瞭優化佈置方案。結果錶明:通過調整引航道中心線位置、縮小引航道中心線與河道主流流嚮交角,併適噹開挖跼部高地,有效地改善瞭上遊引航道通航水流條件;下遊引航道通航水流條件則主要以外擴式底部透空導流牆整流措施來改善。

Due to the location of the approaching channel entrances of Xiajiang Hydro-junction which is located in a S-shaped reach of Gan river ,the navigable flow condition is very complex .Therefore ,a series of physical model tests were conducted to study the measures to improve the navigable flow condition .Based on the test results of different schemes , it is suggested that to improve the flow condition at the upstream entrance area ,adjusting the approaching channel center-line combined with decreasing the angle between the channel centerline and mainstream direction should be taken as the main measures ,and supplemented by excavating local highland ;in addition ,to improve the downstream flow condition , gradually expanded guide wall with permeable bottom should be the major measure .
