摘要
柳江红花枢纽是柳江规划梯级枢纽的最后一级,其坝下至石龙三江口河段受红花枢纽和大藤峡水利枢纽调度的双重影响,水文条件复杂。随着大藤峡水利枢纽的建成运行,红花枢纽坝下至石龙三江口河段亟需将航道等级提升至内河Ⅱ级航道。文章结合枢纽的调度运行方式,建立平面二维水流数学模型,对该河段的设计最低通航水位进行研究,得到经济合理的设计最低通航水位,成果可为类似的河流提供参考。
The Honghua dam is the lowermost cascade hydropower station of the Liujiang River.The waterway between the Honghua dam and Shilong Sanjiangkou is affected by the combined actions of Honghua and Datengxia hydropower station,and the hydrological conditions for navigation are complex.With the impoundment of the Datengxia project,it was urgent to upgrade this navigation channel to the ClassⅡinland waterway.Based on the dispatching operation rules of the reservoirs,a two-dimensional flow mathematical model was established to study the design lowest navigable water level,and the findings could be a useful reference for other similar rivers.
