已建枢纽船闸下游引航道口门区急流碍航改善措施的研究

过去国内内河枢纽建设往往多以防洪、发电等效益为主,航运建设得不到应有的重视,出现了一批碍航闸坝。以已建沅水五强溪枢纽船闸下游引航道口门区通航条件改善措施研究成果为基础,分析了已建五强溪船闸碍航原因,并提出了采用浮式导堤方案解决已建船闸下游引航道口门区急流碍航的工程措施,为今后拟建枢纽的开发建设和其它已建类似碍航枢纽下游航道通航条件改善提供借鉴。

Study on improvement measures of jet flow navigation obstruction for the lower approach entrance area of existed lock

Our country inland junction construction often gave priority to the benefit of controlling flood,generating electricity etc in the past,and insufficient attention was given to navigation construction then a group of navigation-obstruction gate dams have appeared.Based on research results of the study on improvement measures of navigable flow condition for the lower approach entrance area of the existed Wuqiangxi junction lock,the navigation-obstruction reasons have been analyzed.The engineering measure has been brought forward adopting floating embankment scheme to solve jet flow navigation obstruction of the lower approach entrance area of existed lock.It will offer reference for junction construction and the improvement of navigable flow condition for the lower channel of other similar existed navigation-obstruction junctions in the future.
