变高式导堤和导流墩在峡谷枢纽船闸下引航道中的应用

摘要

Taking the canyon section of Guangxi Datengxia hydro-junction in Qianjiang River as an example,by altering the elevation,the arrangement of variable elevation jetty and submerged type diversion pier was adopted in this paper. Then the flood route was adjusted to solve the navigation obstruction problem in middle and dry seasons, and the navigation flow condition of channel and the flood discharge condition of river in the flood period were also improved.%以广西黔江大藤峡枢纽所处峡谷段为例,通过改变导堤和导流墩的高度,采用变高式导堤和淹没式导流墩布置,配合调整洪水航线,解决了中枯水期航道的碍航问题,同时改善了洪水期航道通航水流条件和河道泄洪条件.
