摘　　要：通过对原有白石窑水利枢纽船闸进行改扩建来提高航运能力,将原来的一线船闸改建,同时在改建船闸左岸增设二线船闸。根据白石窑水利枢纽通航建筑物的整体定床模型试验成果,研究该工程改扩建后的通航条件。针对由于枢纽下游主河槽与船闸轴线交角较大以及枢纽下游主河槽河床高出下引航道口门区较多而引起的船闸下游口门区及连接段的斜流、乱流等不利通航水流条件,提出了合理有效的整改措施。该试验成果可供以后类似工程参考和借鉴。We must take further channel regulation measures to improve the navigation environment of the hydro-junction, increase the shipping capacity of the original first-line ship lock by reconstruction and extension, and add the additional second-line ship lock on left bank of the new ship lock. According to the test results of the overall fixed-bed model of navigation building on Baishiyao hydro-junction, we study the navigation conditions after the reconstruction and extension project. For the unfavorable flow condition, we put forward reasonable and effective measures, which may be used as reference for similar projects.
